${{\widetilde{\boldsymbol \chi}}_{{1}}^{\pm}}$, ${{\widetilde{\boldsymbol \chi}}_{{2}}^{\pm}}$ (Charginos) mass limits INSPIRE search

Charginos are unknown mixtures of w-inos and charged higgsinos (the supersymmetric partners of ${{\mathit W}}$ and Higgs bosons). A lower mass limit for the lightest chargino (${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$) of approximately 45 GeV, independent of the field composition and of the decay mode, has been obtained by the LEP experiments from the analysis of the ${{\mathit Z}}$ width and decays. These results, as well as other now superseded limits from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ collisions at energies below 136$~$GeV, and from hadronic collisions, can be found in the 1998 Edition (The European Physical Journal C3 1 (1998)) of this Review.

Unless otherwise stated, results in this section assume spectra, production rates, decay modes and branching ratios as evaluated in the MSSM, with gaugino and sfermion mass unification at the GUT scale. These papers generally study production of ${{\widetilde{\mathit \chi}}_{{1}}^{0}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ , ${{\widetilde{\mathit \chi}}_{{1}}^{+}}{{\widetilde{\mathit \chi}}_{{1}}^{-}}$ and (in the case of hadronic collisions) ${{\widetilde{\mathit \chi}}_{{1}}^{+}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ pairs, including the effects of cascade decays. The mass limits on ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ are either direct, or follow indirectly from the constraints set by the non-observation of ${{\widetilde{\mathit \chi}}_{{2}}^{0}}$ states on the gaugino and higgsino MSSM parameters $\mathit M_{2}$ and $\mu $. For generic values of the MSSM parameters, limits from high-energy ${{\mathit e}^{+}}{{\mathit e}^{-}}$ collisions coincide with the highest value of the mass allowed by phase-space, namely ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}{ {}\lesssim{} }\sqrt {s }$/2. The still unpublished combination of the results of the four LEP collaborations from the 2000 run of LEP2 at $\sqrt {\mathit s }$ up to $\simeq{}209~$GeV yields a lower mass limit of 103.5$~$GeV valid for general MSSM models. The limits become however weaker in certain regions of the MSSM parameter space where the detection efficiencies or production cross sections are suppressed. For example, this may happen when: (i)$~$the mass differences $\Delta \mathit m_{+}$= ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}–{\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ or $\Delta {\mathit m}_{{{\mathit \nu}}}$= ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}–{\mathit m}_{{{\widetilde{\mathit \nu}}}}$ are very small, and the detection efficiency is reduced; (ii)$~$the electron sneutrino mass is small, and the ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ production rate is suppressed due to a destructive interference between ${{\mathit s}}$ and ${{\mathit t}}$ channel exchange diagrams. The regions of MSSM parameter space where the following limits are valid are indicated in the comment lines or in the footnotes.

Some earlier papers are now obsolete and have been omitted. They were last listed in our PDG 2014 edition: K. Olive, $\mathit et~al.$ (Particle Data Group), Chinese Physics C38 070001 (2014) (http://pdg.lbl.gov).

No significant excess above the Standard Model expectations is observed. Limits are set on chargino masses in a general gauge-mediated SUSY breaking (GGM) scenario Tchi1n12-GGM, see Figure 4. Limits are also set on the NLSP mass in the Tchi1chi1F and Tchi1chi1G simplified models, see their Figure 5. Finally, limits are set on the gluino mass in the Tglu4A simplified model, see Figure 6.

Fully hadronic, semileptonic, diphoton, and multilepton (electrons, muons) final states with missing transverse momentum are considered in this search. Observations are consistent with the Standard Model expectations, and 95$\%$ confidence-level limits of up to 680 GeV on the chargino/next-to-lightest neutralino masses are set (Tchi1n2E model).

Assuming decays via intermediate ${{\widetilde{\mathit \tau}}_{{L}}}$ and ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}$ = ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{2}}^{0}}}$, the observed limits rule out ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ masses up to 760 GeV for a massless ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$. See their Fig.7 (right). Interpretations are also provided in Fig 8 (bottom) for different assumptions on the ratio between ${\mathit m}_{{{\widetilde{\mathit \tau}}}}$ and ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}$ + ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$.

Limits are set on the chargino mass up to 600 GeV for massless neutralinos in the Tchi1n2F simplified model exploiting the statistical combination of 2${{\mathit \ell}}$+2 jets and 3${{\mathit \ell}}$ channels. Chargino masses below 220 GeV are not excluded due to an excess of events above the SM prediction in the dedicated regions. See their Figure 13(d).

No significant excess of events is observed above the SM prediction. Results of the diphoton channel are interpreted in terms of lower limits on the masses of gauginos Tchi1chi1A models, which reach as high as 1.3 TeV. Gaugino masses below 1060 GeV are excluded for any NLSP mass, see their Fig. 10.

34  KHACHATRYAN 2014L searched in 19.5 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for evidence of chargino-neutralino ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ pair production with Higgs or ${{\mathit W}}$-bosons in the decay chain, leading to ${{\mathit H}}{{\mathit W}}$ final states with missing transverse energy. The decays of a Higgs boson to a photon pair are considered in conjunction with hadronic and leptonic decay modes of the ${{\mathit W}}$ bosons. No significant excesses over the expected SM backgrounds are observed. The results are interpreted in the context of simplified models where the decays ${{\widetilde{\mathit \chi}}_{{2}}^{0}}$ $\rightarrow$ ${{\mathit H}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ and ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ $\rightarrow$ ${{\mathit W}^{\pm}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ take place 100$\%$ of the time, see Figs. $22 - 23$.

No excess beyond the Standard Model expectation is observed. Exclusion limits are derived in the phenomenological MSSM, see Fig. 2 and 3, and in simplified models, see Fig. 4. For the simplified models with intermediate slepton decays, degenerate ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ and ${{\widetilde{\mathit \chi}}_{{2}}^{0}}$ masses up to 500 GeV are excluded at 95$\%$ C.L. for very large mass differences with the ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$.

No excess beyond the Standard Model expectation is observed. Limits are derived in a simplified model of wino-like chargino pair production, where the chargino always decays to the lightest neutralino via an intermediate on-shell charged slepton, see Fig. 2(b). Chargino masses between 110 and 340 GeV are excluded at 95$\%$ C.L. for ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ = 10 GeV. Exclusion limits are also derived in the phenomenological MSSM, see Fig. 3.

No significant excess is found in the data. Limits are presented in a simplified model of R-parity violating supersymmetry in which charginos are pair-produced and then decay into a ${{\mathit W}}$-boson and a ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$, which in turn decays through an RPV coupling into two charged leptons ( ${{\mathit e}^{\pm}}{{\mathit e}^{\mp}}$ or ${{\mathit e}^{\pm}}{{\mathit \mu}^{\mp}}$ ) and a neutrino. In this model, chargino masses up to 540 GeV are excluded at 95$\%$ C.L. for ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ above 300 GeV, see Fig. 3a. The limit deteriorates for lighter ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$. Limits are also set in an R-parity violating mSUGRA model, see Fig. 3b.

No significant excesses over the expected SM backgrounds are observed and 95$\%$ C.L. limits on the production cross section of ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ pair production were set in a number of simplified models, see Figs. 7 to 12.
39  ABDALLAH 2003M uses data from $\sqrt {s }$ = $192 - 208$ GeV to obtain limits in the framework of the MSSM with gaugino and sfermion mass universality at the GUT scale. An indirect limit on the mass of charginos is derived by constraining the MSSM parameter space by the results from direct searches for neutralinos (including cascade decays), for charginos and for sleptons. These limits are valid for values of $\mathit M_{2}<$ 1 TeV, $\vert {{\mathit \mu}}\vert {}\leq{}$2 TeV with the ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$ as LSP. Constraints from the Higgs search in the $\mathit m{}^{{\mathrm {max}}}_{h}$ scenario assuming ${\mathit m}_{{{\mathit t}}}$= 174.3$~$GeV are included. The quoted limit applies if there is no mixing in the third family or when ${\mathit m}_{{{\widetilde{\mathit \tau}}_{{1}}}}\text{-}{\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}>$ 6 GeV. If mixing is included the limit degrades to 90 GeV. See Fig.~43 for the mass limits as a function of tan $\beta $. These limits update the results of ABREU 2000W.
40  KHACHATRYAN 2016AA searched in 7.4 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for events with one or more photons, hadronic jets and $\not E_T$. No significant excess above the Standard Model expectations is observed. Limits are set on wino masses in the general gauge-mediated SUSY breaking model (GGM), for a wino-like neutralino NLSP scenario and with the wino mass fixed at 10 GeV above the bino mass, see Fig. 4. Limits are also set in the Tchi1chi1A and Tchi1n1A simplified models, see Fig. 3.
41  KHACHATRYAN 2016R searched in 19.7 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for events with one or more photons, one electron or muon, and $\not E_T$. No significant excess above the Standard Model expectations is observed. Limits are also set in the Tglu1F simplified model, see Fig. 6.
42  KHACHATRYAN 2016Y searched in 19.7 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for events with one or two soft isolated leptons, hadronic jets, and $\not E_T$. No significant excess above the Standard Model expectations is observed. Limits are set on the ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ mass (which is degenerate with the ${{\widetilde{\mathit \chi}}_{{2}}^{0}}$) in the Tchi1n2A simplified model, see Fig. 4.
43  AAD 2014AV searched in 20.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for the direct production of charginos, neutralinos and staus in events containing at last two hadronically decaying ${{\mathit \tau}}$-leptons, large missing transverse momentum and low jet activity. The quoted limit was derived for direct ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ and ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{1}}^{\mp}}$ production with ${{\widetilde{\mathit \chi}}_{{2}}^{0}}$ $\rightarrow$ ${{\widetilde{\mathit \tau}}}{{\mathit \tau}}$ $\rightarrow$ ${{\mathit \tau}}{{\mathit \tau}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ and ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ $\rightarrow$ ${{\widetilde{\mathit \tau}}}{{\mathit \nu}}$( ${{\widetilde{\mathit \nu}}_{{\tau}}}{{\mathit \tau}}$) $\rightarrow$ ${{\mathit \tau}}{{\mathit \nu}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ , ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{2}}^{0}}}$ = ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}$, ${\mathit m}_{{{\widetilde{\mathit \tau}}}}$ = 0.5 (${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}$ + ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$), ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ = 0 GeV. No excess over the expected SM background is observed. Exclusion limits are set in simplified models of ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{1}}^{\mp}}$ and ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ pair production, see their Figure 7. Upper limits on the cross section and signal strength for direct di-stau production are derived, see Figures 8 and 9. Also, limits are derived in a pMSSM model where the only light slepton is the ${{\widetilde{\mathit \tau}}_{{R}}}$, see Figure 10.
44  AAD 2014AV searched in 20.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for the direct production of charginos, neutralinos and staus in events containing at last two hadronically decaying ${{\mathit \tau}}$-leptons, large missing transverse momentum and low jet activity. The quoted limit was derived for direct ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{1}}^{\mp}}$ production with ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ $\rightarrow$ ${{\widetilde{\mathit \tau}}}{{\mathit \nu}}$( ${{\widetilde{\mathit \nu}}_{{\tau}}}{{\mathit \tau}}$) $\rightarrow$ ${{\mathit \tau}}{{\mathit \nu}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ , ${\mathit m}_{{{\widetilde{\mathit \tau}}}}$ = 0.5 (${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}}$ + ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$), ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ = 0 GeV. No excess over the expected SM background is observed. Exclusion limits are set in simplified models of ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{1}}^{\mp}}$ and ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ pair production, see their Figure 7. Upper limits on the cross section and signal strength for direct di-stau production are derived, see Figures 8 and 9. Also, limits are derived in a pMSSM model where the only light slepton is the ${{\widetilde{\mathit \tau}}_{{R}}}$, see Figure 10.
45  AAD 2014G searched in 20.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for electroweak production of chargino pairs, or chargino-neutralino pairs, decaying to a final sate with two leptons (${{\mathit e}}$ and ${{\mathit \mu}}$) and missing transverse momentum. No excess beyond the Standard Model expectation is observed. Exclusion limits are derived in simplified models of chargino pair production, with chargino decays to the lightest neutralino via either sleptons or gauge bosons, see Fig 5.; or in simplified models of chargino and next-to-lightest neutralino production, with decays to the lightest neutralino via gauge bosons, see Fig. 7. An interpretation in the pMSSM is also given, see Fig. 10.
46  AALTONEN 2014 searched in 5.8 fb${}^{-1}$ of ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV for evidence of chargino and next-to-lightest neutralino associated production in final states consisting of three leptons (electrons, muons or taus) and large missing transverse momentum. The results are consistent with the Standard Model predictions within 1.85 $\sigma $. Limits on the chargino mass are derived in an mSUGRA model with ${\mathit m}_{\mathrm {0}}$ = 60 GeV, tan ${{\mathit \beta}}$ = 3, ${{\mathit A}_{{0}}}$ = 0 and ${{\mathit \mu}}$ $>$0, see their Fig. 2.
47  KHACHATRYAN 2014I searched in 19.5 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for electroweak production of chargino pairs decaying to a final state with opposite-sign lepton pairs (${{\mathit e}}$ or ${{\mathit \mu}}$) and missing transverse momentum. No excess beyond the Standard Model expectation is observed. Exclusion limits are derived in simplified models, see Fig. 18.
48  AALTONEN 2013Q searched in 6.0 fb${}^{-1}$ of ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV for evidence of chargino-neutralino associated production in like-sign dilepton final states. One lepton is identified as the hadronic decay of a tau lepton, while the other is an electron or muon. Good agreement with the Standard Model predictions is observed and limits are set on the chargino-neutralino cross section for simplified gravity- and gauge-mediated models, see their Figs. 2 and 3.
49  AAD 2012AS searched in 2.06 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for charginos and neutralinos decaying to a final state with three leptons (${{\mathit e}}$ and ${{\mathit \mu}}$) and missing transverse energy. No excess beyond the Standard Model expectation is observed. Exclusion limits are derived in the phenomenological MSSM, see Fig. 2 (top), and in simplified models, see Fig. 2 (bottom).
50  AAD 2012T looked in 1 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for the production of supersymmetric particles decaying into final states with missing transverse momentum and exactly two isolated leptons (${{\mathit e}}$ or ${{\mathit \mu}}$). Opposite-sign and same-sign dilepton events were separately studied. Additionally, in opposite-sign events, a search was made for an excess of same-flavor over different-flavor lepton pairs. No excess over the expected background is observed and limits are placed on the effective production cross section of opposite-sign dilepton events with $\not E_T$ $>$ 250 GeV and on same-sign dilepton events with $\not E_T$ $>$ 100 GeV. The latter limit is interpreted in a simplified electroweak gaugino production model as a lower chargino mass limit.
51  CHATRCHYAN 2011B looked in 35 pb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$=7 TeV for events with an isolated lepton (${{\mathit e}}$ or ${{\mathit \mu}}$), a photon and $\not E_T$ which may arise in a generalized gauge mediated model from the decay of Wino-like NLSPs. No evidence for an excess over the expected background is observed. Limits are derived in the plane of squark/gluino mass versus Wino mass (see Fig. 4). Mass degeneracy of the produced squarks and gluinos is assumed.
52  CHATRCHYAN 2011V looked in 35 pb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with ${}\geq{}$3 isolated leptons (${{\mathit e}}$, ${{\mathit \mu}}$ or ${{\mathit \tau}}$), with or without jets and $\not E_T$. No evidence for an excess over the expected background is observed. Limits are derived in the CMSSM (${{\mathit m}_{{0}}}$, ${{\mathit m}_{{1/2}}}$) plane for tan ${{\mathit \beta}}$ = 3 (see Fig. 5).
