${{\widetilde{\mathit q}}}$ (Squark) mass limit

For ${\mathit m}_{{{\widetilde{\mathit q}}}}$ $>$ 60$-$70 GeV, it is expected that squarks would undergo a cascade decay via a number of neutralinos and/or charginos rather than undergo a direct decay to photinos as assumed by some papers. Limits obtained when direct decay is assumed are usually higher than limits when cascade decays are included.
Limits from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ collisions depend on the mixing angle of the lightest mass eigenstate ${{\widetilde{\mathit q}}_{{{1}}}}={{\widetilde{\mathit q}}_{{{R}}}}$sin$\theta _{{{\mathit q}}}+{{\widetilde{\mathit q}}_{{{L}}}}$cos $\theta _{{{\mathit q}}}$. It is usually assumed that only the sbottom and stop squarks have non-trivial mixing angles (see the stop and sbottom sections). Here, unless otherwise noted, squarks are always taken to be either left/right degenerate, or purely of left or right type. Data from ${{\mathit Z}}$ decays have set squark mass limits above 40 GeV, in the case of ${{\widetilde{\mathit q}}}$ $\rightarrow$ ${{\mathit q}}{{\widetilde{\mathit \chi}}_{{{1}}}}$ decays if $\Delta \mathit m={\mathit m}_{{{\widetilde{\mathit q}}}}–{\mathit m}_{{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}}{ {}\gtrsim{} }$5 GeV. For smaller values of $\Delta \mathit m$, current constraints on the invisible width of the ${{\mathit Z}}$ ($\Delta \Gamma _{{\mathrm {inv}}}<2.0$ MeV, LEP 2000) exclude ${\mathit m}_{{{\widetilde{\mathit u}}_{{{L,R}}}}}<$44 GeV, ${\mathit m}_{{{\widetilde{\mathit d}}_{{{R}}}}}<$33 GeV, ${\mathit m}_{{{\widetilde{\mathit d}}_{{{L}}}}}<$44 GeV and, assuming all squarks degenerate, ${\mathit m}_{{{\widetilde{\mathit q}}}}<$45 GeV.
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).

1  AAD 2024Z searched in 139 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV for events with exactly two same-sign leptons or at least three leptons. Several signal regions, including a $\not E_T$ selection targeting RPC models, and selections based on ${{\mathit b}}$-jet multiplicities, targeting RPV models, are considered. No significant excess over the Standard Model expectation is found. Exclusion limits at 95$\%$ C.L. are set on the gluino or squark mass, in multi-step RPC decays via charginos, neutralinos or sleptons into quarks, leptons and neutralinos, or RPV decays of either the neutralino LSP or the stop produced in ${{\widetilde{\mathit g}}}$ $\rightarrow$ ${{\mathit t}}{{\widetilde{\mathit t}}}$ into quarks. See their Fig. 7.
2  HAYRAPETYAN 2024Q searched in 138 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV for evidence of stealth supersymmetry in final states with two photons and jets, and low $\not E_T$. No significant excess above the Standard Model expectations is observed. The investigated models include a singlet scalar boson ${{\mathit S}}$, and its SUSY fermion ${{\widetilde{\mathit S}}}$. In the investigated models, either gluinos or squarks are pair produced and each decay to a ${{\widetilde{\mathit \chi}}_{{{1}}}^{0}}$ and a gluon or squark, respectively, followed by the decays ${{\widetilde{\mathit \chi}}_{{{1}}}^{0}}$ $\rightarrow$ ${{\mathit \gamma}}{{\widetilde{\mathit S}}}$, ${{\widetilde{\mathit S}}}$ $\rightarrow$ ${{\widetilde{\mathit G}}}{{\mathit S}}$ and ${{\mathit S}}$ $\rightarrow$ ${{\mathit g}}{{\mathit g}}$.

This search targets ${{\mathit H}_{{{1}}}}$ decays to ${{\mathit b}}{{\overline{\mathit b}}}$-pairs that are reconstructed in large-area (AK8) jets. No significant excess above the Standard Model expectations is observed. Limits are set in the next-to-minimal supersymmetric extension of the SM, where a singlino of small mass leads to squark and gluino cascade decays that can predominantly end in a highly Lorentz-boosted singlet-like ${{\mathit H}_{{{1}}}}$ and a singlino-like neutralino ${{\widetilde{\mathit \chi}}_{{{S}}}^{0}}$ of small transverse momentum.

The data are found to be consistent with the SM expectation. Results are interpreted in the Tsqk2 model in case of ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}}$ = 1 GeV: for any ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{2}}}^{0}}}$, squark masses below 1200 GeV are excluded, see their Fig. 14(b).

In scenarios with massless neutralinos, scharm masses below 850 GeV are excluded. If the differences of the ${{\widetilde{\mathit c}}_{{{1}}}}$ and ${{\widetilde{\mathit \chi}}_{{{1}}}^{0}}$ masses is below 100 GeV, scharm masses below 500 GeV are excluded.

No excess over the expected SM background is observed.

Such signatures may originate from supersymmetric models with gauge-mediated supersymmetry breaking in events in which one of a pair of higgsino-like neutralinos decays into a photon and a gravitino while the other decays into a Higgs boson and a gravitino. No significant excess above the expected background was found and limits were set on the squark mass as a function of the neutralino mass in a generalized GMSB model (GGM) with a higgsino-like neutralino NLSP, see their Fig. 4.

Limits are set on squark masses in simplified models where the decay ${{\widetilde{\mathit q}}}$ $\rightarrow$ ${{\mathit q}}{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}$ takes place with a branching ratio of 100$\%$, assuming an eightfold degeneracy of the masses of the first two generation squarks, see Fig. 8 and Table 9. Also limits in the case of a single light squark are given.
43  AAD 2012AX searched in 1.04 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for supersymmetry in events containing jets, missing transverse momentum and one isolated electron or muon. No excess over the expected SM background is observed and model-independent limits are set on the cross section of new physics contributions to the signal regions. In mSUGRA/CMSSM models with tan ${{\mathit \beta}}$ = 10, ${{\mathit A}_{{{0}}}}$ = 0 and ${{\mathit \mu}}$ $>$ 0, squarks and gluinos of equal mass are excluded for masses below 820 GeV at 95$\%$ C.L. Limits are also set on simplified models for squark production and decay via an intermediate chargino and on supersymmetric models with bilinear R-parity violation. Supersedes AAD 2011G.
44  AAD 2012CJ searched in 4.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events containing one or more isolated leptons (electrons or muons), jets and $\not E_T$. The observations are in good agreement with the SM expectations and exclusion limits have been set in number of SUSY models. In the mSUGRA/CMSSM model with tan ${{\mathit \beta}}$ = 10, ${{\mathit A}_{{{0}}}}$ = 0, and ${{\mathit \mu}}$ $>$ 0, 95$\%$ C.L. exclusion limits have been derived for ${\mathit m}_{{{\widetilde{\mathit q}}}}$ $<$ 1200 GeV, assuming equal squark and gluino masses. In minimal GMSB, values of the effective SUSY breaking scale ${{\mathit \Lambda}}$ $<$ 50 TeV are excluded at 95$\%$ C.L. for tan ${{\mathit \beta}}$ $<$ 45. Also exclusion limits in a number of simplified models have been presented, see Figs. 10 and 12.
45  AAD 2012CP searched in 4.8 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with two photons and large $\not E_T$ due to ${{\widetilde{\mathit \chi}}_{{{1}}}^{0}}$ $\rightarrow$ ${{\mathit \gamma}}{{\widetilde{\mathit G}}}$ decays in a GMSB framework. No significant excess above the expected background was found and limits were set on the squark mass as a function of the neutralino mass in a generalized GMSB model (GGM) with a bino-like neutralino NLSP. The other sparticle masses were decoupled, tan ${{\mathit \beta}}$ = 2 and ${{\mathit c}}{{\mathit \tau}_{{{NLSP}}}}$ $<$ 0.1 mm. Also, in the framework of the SPS8 model, a 95$\%$ C.L. lower limit was set on the breaking scale ${{\mathit \Lambda}}$ of 196 TeV.
46  AAD 2012W searched in 1.04 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for the production of squarks and gluinos in events containing jets, missing transverse momentum and no electrons or muons. No excess over the expected SM background is observed. In mSUGRA/CMSSM models with tan ${{\mathit \beta}}$ = 10, ${{\mathit A}_{{{0}}}}$ = 0 and ${{\mathit \mu}}$ $>$ 0, squarks and gluinos of equal mass are excluded for masses below 950 GeV at 95$\%$ C.L. In a simplified model containing only squarks of the first two generations, a gluino octet and a massless neutralino, squark masses below 875 GeV are excluded at 95$\%$ C.L.
47  CHATRCHYAN 2012 looked in 35 pb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with ${{\mathit e}}$ and/or ${{\mathit \mu}}$ and/or jets, a large total transverse energy, and $\not E_T$. The event selection is based on the dimensionless razor variable ${{\mathit R}}$, related to the $\not E_T$ and ${{\mathit M}_{{{R}}}}$, an indicator of the heavy particle mass scale. 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, 10 and 50 (see Fig. 7 and 8). Limits are also obtained for Simplified Model Spectra.

For ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}}$ $<$ 200 GeV, values of ${\mathit m}_{{{\widetilde{\mathit q}}}}$ below 760 GeV are excluded at 95$\%$ C.L. Also limits in the CMSSM are presented, see Fig. 2.

No excess over the expected SM background is observed. In mSUGRA/CMSSM models with tan $\beta $ = 10, ${{\mathit A}_{{{0}}}}$ = 0 and ${{\mathit \mu}}$ $>$ 0, squarks with masses below 1110 GeV are excluded at 95$\%$ C.L.

The data are found to be consistent with the SM expectation. Results are interpreted in the Tsqk5 model. Squark masses below 1100 GeV are excluded if (${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{2}}}^{0}}}$ $−$ ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}})/({\mathit m}_{{{\widetilde{\mathit q}}}}$ $−$ ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}}$) $<$ 0.95 and ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}}$ = 60 GeV, see their Fig. 16(a).
