# ${{\widetilde{\boldsymbol b}}}$ (Sbottom) mass limit

Limits in ${{\mathit e}^{+}}{{\mathit e}^{-}}$ depend on the mixing angle of the mass eigenstate ${{\widetilde{\mathit b}}_{{1}}}$ = ${{\widetilde{\mathit b}}_{{L}}}$cos $\theta _{{{\mathit b}}}$ $+$ ${{\widetilde{\mathit b}}_{{R}}}$sin$\theta _{{{\mathit b}}}$. Coupling to the ${{\mathit Z}}$ vanishes for $\theta _{{{\mathit b}}}\sim{}1.17$. As a consequence, no absolute constraint in the mass region ${ {}\lesssim{} }$40 GeV is available in the literature at this time from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ collisions. In the Listings below, we use $\Delta \mathit m$ = ${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}}–{\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$.
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).

11  AABOUD 2016D searched in 3.2 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV for events with an energetic jet and large missing transverse momentum. The results are interpreted as 95$\%$C.L. limits on mass of sbottom decaying into a ${{\mathit b}}$-quark and the lightest neutralino in scenarios with ${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}}−$ ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ between 5 and 20 GeV.

12  AABOUD 2016Q searched in 3.2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV for events containing two jets identified as originating from ${{\mathit b}}$-quarks and large missing transverse momentum. No excess of events above the expected level of Standard Model background was found. Exclusion limits at 95$\%$ C.L. are set on the masses of third-generation squarks. Assuming that the decay ${{\widetilde{\mathit b}}_{{1}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ (Tsbot1) takes place 100$\%$ of the time, a ${{\widetilde{\mathit b}}_{{1}}}$ mass below 840 (800) GeV is excluded for ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}<$ 100 (360) GeV. Differences in mass above 100 GeV between the ${{\widetilde{\mathit b}}_{{1}}}$ and the ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$ are excluded up to a ${{\widetilde{\mathit b}}_{{1}}}$ mass of 500 GeV. For more details, see their Fig. 4.

See their Fig. 4c.

17  AAD 2015CJ searched in 20 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for evidence of third generation squarks by combining a large number of searches covering various final states. Limits on the sbottom mass are shown, either assuming the ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit b}}$ ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$ decay, see Fig. 11, or assuming the ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit t}}{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ decay, with ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ $\rightarrow$ ${{\mathit W}^{(*)}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ , see Fig. 12a, or assuming the ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ decay, with ${{\widetilde{\mathit \chi}}_{{2}}^{0}}$ $\rightarrow$ ${{\mathit h}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ , see Fig. 12b.

No significant excess above the Standard Model expectations is observed. Limits are set on the sbottom mass in simplified models where the decay ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ takes place with a branching ratio of 100$\%$, see Fig. 12. See also Table 5. Exclusions in the CMSSM, assuming tan ${{\mathit \beta}}$ = 30, $\mathit A_{0}$ = $−$2 max(${\mathit m}_{\mathrm {0}}$, ${\mathit m}_{\mathrm {1/2}}$) and ${{\mathit \mu}}$ $>$ 0, are also presented, see Fig. 15.

No significant excess above the Standard Model expectations is observed. Limits are set on the sbottom mass in simplified models where the decay ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ takes place with a branching ratio of 100$\%$, see Fig. 12. Limits are also set in a simplified model where the decay ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit c}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ takes place with a branching ratio of 100$\%$, see Fig. 12.
20  KHACHATRYAN 2015I searched in 19.5 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for events in which ${\mathit {\mathit b}}$-jets and four ${{\mathit W}}$-bosons are produced. Five individual search channels are combined (fully hadronic, single lepton, same-sign dilepton, opposite-sign dilepton, multilepton). No significant excess above the Standard Model expectations is observed. Limits are set on the sbottom mass in a simplified model where the decay ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit t}}{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ , with ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ $\rightarrow$ ${{\mathit W}^{\pm}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ , takes place with a branching ratio of 100$\%$, see Fig. 7.
21  AAD 2014T searched in 20.3 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for monojet-like events. No excess of events above the expected level of Standard Model background was found. Exclusion limits at 95$\%$ C.L. are set on the masses of third-generation squarks in simplified models which assume that the decay ${{\widetilde{\mathit b}}_{{1}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ takes place 100$\%$ of the time, see Fig. 12.
22  CHATRCHYAN 2014AH searched in 4.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with at least two energetic jets and significant $\not E_T$, using the razor variables (${{\mathit M}_{{R}}}$ and ${{\mathit R}^{2}}$) to discriminate between signal and background processes. A second analysis requires at least one of the jets to be originating from a ${{\mathit b}}$-quark. No significant excess above the Standard Model expectations is observed. Limits are set on sbottom masses in simplified models where the decay ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ takes place with a branching ratio of 100$\%$, see Figs. 28 and 29. Exclusions in the CMSSM, assuming tan $\beta$ = 10, ${{\mathit A}_{{0}}}$ = 0 and ${{\mathit \mu}}$ $>$0, are also presented, see Fig. 26.

No significant excess above the Standard Model expectations is observed. Limits are set on the gluino mass in a simplified model where the decay ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit t}}{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ , with ${{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ $\rightarrow$ ${{\mathit W}^{\pm}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ , takes place with a branching ratio of 100$\%$, see Fig. 11.

No evidence for a statistically significant excess over the expected SM backgrounds is observed and 95$\%$ C.L. exclusion limits are derived in a simplified model of sbottom pair production where the sbottom decays into a ${\mathit {\mathit b}}$-quark, two opposite-sign dileptons and a neutralino LSP, through an intermediate state containing either an off-shell ${{\mathit Z}}$-boson or a slepton, see Fig. 8.

No excess over the expected SM background is observed. Limits are derived in mSUGRA/CMSSM models with tan $\beta$ = 30, ${{\mathit A}_{{0}}}$ = $-2$ ${{\mathit m}_{{0}}}$ and ${{\mathit \mu}}$ $>$ 0, see their Fig. 14. Also, exclusion limits are set in simplified models containing scalar bottom quarks, where the decay ${{\widetilde{\mathit b}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{2}}^{0}}$ and ${{\widetilde{\mathit \chi}}_{{2}}^{0}}$ $\rightarrow$ ${{\mathit h}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ takes place with a branching ratio of 100$\%$, see their Figures 11.

No excess of events above the expected level of Standard Model background was found. Exclusion limits at 95$\%$ C.L. are set on the masses of third-generation squarks. Assuming that the decay ${{\widetilde{\mathit b}}_{{1}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ takes place 100$\%$ of the time, a ${{\widetilde{\mathit b}}_{{1}}}$ mass below 620 GeV is excluded for ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}<$ 120 GeV. For more details, see their Fig. 5.
29  CHATRCHYAN 2013AT provides interpretations of various searches for supersymmetry by the CMS experiment based on $4.73 - 4.98$ fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV in the framework of simplified models.

31  CHATRCHYAN 2013V searched in 10.5 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for events with two isolated same-sign dileptons and at least two ${{\mathit b}}$-jets in the final state. No significant excess above the Standard Model expectations is observed.

The data are found to be consistent with the Standard Model expectations. Limits are set in an R-parity conserving minimal supersymmetric scenario, assuming B( ${{\widetilde{\mathit b}}_{{1}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ ) = 100$\%$, see their Fig. 2.
33  CHATRCHYAN 2012AI looked in 4.98 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with two same-sign leptons (${{\mathit e}}$, ${{\mathit \mu}}$), but not necessarily same flavor, at least 2 ${{\mathit b}}$-jets and missing transverse energy. No excess beyond the Standard Model expectation is observed. Exclusion limits are derived in a simplified model for sbottom pair production, where the sbottom decays through ${{\widetilde{\mathit b}}_{{1}}}$ $\rightarrow$ ${{\mathit t}}{{\widetilde{\mathit \chi}}_{{1}}}{{\mathit W}}$ , see Fig. 8.
34  CHATRCHYAN 2012BO searched in 4.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for scalar bottom quarks in events with large missing transverse momentum and two ${{\mathit b}}$-jets in the final state. The data are found to be consistent with the Standard Model expectations. Limits are set in an R-parity conserving minimal supersymmetric scenario, assuming B( ${{\widetilde{\mathit b}}_{{1}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ ) = 100$\%$, see their Fig. 2.
35  AAD 2011K looked in 34 pb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with heavy stable particles, identified by their anomalous dE/dx in the tracker or time of flight in the tile calorimeter, from pair production of ${{\widetilde{\mathit b}}}$. No evidence for an excess over the SM expectation is observed and limits on the mass are derived for pair production of sbottom, see Fig. 4.
36  AAD 2011O looked in 35 pb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with jets, of which at least one is a ${{\mathit b}}$-jet, and $\not E_T$. No excess above the Standard Model was found. Limits are derived in the (${\mathit m}_{{{\widetilde{\mathit g}}}}$, ${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}}$) plane (see Fig. 2) under the assumption of 100$\%$ branching ratios and ${{\widetilde{\mathit b}}_{{1}}}$ being the lightest squark. The quoted limit is valid for ${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}}$ $<$ 500 GeV. A similar approach for ${{\widetilde{\mathit t}}_{{1}}}$ as the lightest squark with ${{\widetilde{\mathit g}}}$ $\rightarrow$ ${{\widetilde{\mathit t}}_{{1}}}{{\mathit t}}$ and ${{\widetilde{\mathit t}}_{{1}}}$ $\rightarrow$ ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{\pm}}$ with 100$\%$ branching ratios leads to a gluino mass limit of 520 GeV for 130 $<$ ${\mathit m}_{{{\widetilde{\mathit t}}_{{1}}}}$ $<$ 300 GeV. Limits are also derived in the CMSSM (${{\mathit m}_{{0}}}$, ${{\mathit m}_{{1/2}}}$) plane for tan ${{\mathit \beta}}$ = 40, see Fig. 4, and in scenarios based on the gauge group SO(10).
37  CHATRCHYAN 2011D looked in 35 pb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with ${}\geq{}$ 2 jets, at least one of which is b-tagged, and $\not E_T$, where the ${{\mathit b}}$-jets are decay products of ${{\widetilde{\mathit t}}}$ or ${{\widetilde{\mathit b}}}$. 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 ${{\mathit \beta}}$ = 50 (see Fig. 2).
38  AALTONEN 2010R searched in 2.65 fb${}^{-1}$ of ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV for events with $\not E_T$ and exactly two jets, at least one of which is ${{\mathit b}}$-tagged. The results are in agreement with the SM prediction, and a limit on the cross section of 0.1 pb is obtained for the range of masses 80 $<$ ${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}}<$ 280 GeV assuming that the sbottom decays exclusively to ${{\mathit b}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ . The excluded mass region in the framework of conserved ${{\mathit R}_{{p}}}$ is shown in a plane of (${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}}$, ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$), see their Fig.2.
39  ABAZOV 2010L looked in 5.2 fb${}^{-1}$ of ${{\mathit p}}{{\overline{\mathit p}}}$ collisions at $\sqrt {s }$ = 1.96 TeV for events with at least 2 b-jets and $\not E_T$ from the production of ${{\widetilde{\mathit b}}_{{1}}}{{\widetilde{\mathit b}}_{{1}}}$ . No evidence for an excess over the SM expectation is observed, and a limit on the cross section is derived under the assumption of 100$\%$ branching ratio. The excluded mass region in the framework of conserved ${{\mathit R}_{{p}}}$ is shown in a plane of (${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}},{\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$), see their Fig. 3b. The exclusion also extends to ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ = 110 GeV for 160$<$ ${\mathit m}_{{{\widetilde{\mathit b}}_{{1}}}}$ $<$ 200 GeV.
