${{\widetilde{\mathit b}}}$ (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).

Limits are also set on the sbottom mass in the Tsbot2 simplified model, see their Figure 10, and on the stop mass in the Tstop7 simplified model, see their Figure 11. Finally, limits are set on the gluino mass in RPV simplified models where the gluino decays either via ${{\widetilde{\mathit g}}}$ $\rightarrow$ ${{\mathit q}}{{\mathit q}}{{\overline{\mathit q}}}{{\overline{\mathit q}}}{+}$ ${{\mathit e}}$ $/$ ${{\mathit \mu}}$ $/$ ${{\mathit \tau}}$ or via ${{\widetilde{\mathit g}}}$ $\rightarrow$ ${{\mathit t}}{{\mathit b}}{{\mathit s}}$, see Figure 12.

Higgs boson candidates are reconstructed as ${{\mathit b}}$-jet pairs. No significant excess above the Standard Model expectations is observed.

No significant excess above the Standard Model expectations is observed. Limits are set on the sbottom mass in the Tsbot4 simplified model, see Figure 3, and on the wino mass in the Tchi1n2E simplified model, see their Figure 4. Limits are also set on the higgsino mass in the Tn1n1A and Tn1n1B simplified models, see their Figure 5.
10  AABOUD 2018I searched in 36.1 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV for events with at least one jet with a transverse momentum above 250 GeV and no leptons. Good agreement is observed between the number of events in data and Standard Model predictions. The results are translated into exclusion limits in Tsbot1 models. In the compressed scenario with sbottom and neutralino masses differing by ${\mathit m}_{{{\mathit b}}}$, sbottom masses below 430 GeV are excluded. For ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{{1}}}^{0}}}$ = 0 they exclude sbottom masses up to 610 GeV. See their Fig.10(a).

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.
53  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.
