Search for squarks and gluinos in final states with hadronically decaying $τ$-leptons, jets, and missing transverse momentum using $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector
A search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying $τ$-lepton is presented. Two exclusive final states with either exactly one or at least two $τ$-leptons are considered. The analysis is based on proton-proton collisions at $\sqrt{s}$ = 13 TeV corresponding to an integrated luminosity of 36.1 fb$^{-1}$ delivered by the Large Hadron Collider and recorded by the ATLAS detector in 2015 and 2016. No significant excess is observed over the Standard Model expectation. At 95% confidence level, model-independent upper limits on the cross section are set and exclusion limits are provided for two signal scenarios: a simplified model of gluino pair production with $τ$-rich cascade decays, and a model with gauge-mediated supersymmetry breaking (GMSB). In the simplified model, gluino masses up to 2000 GeV are excluded for low values of the mass of the lightest supersymmetric particle (LSP), while LSP masses up to 1000 GeV are excluded for gluino masses around 1400 GeV. In the GMSB model, values of the supersymmetry-breaking scale are excluded below 110 TeV for all values of $\tanβ$ in the range $2 \leq \tanβ\leq 60$, and below 120 TeV for $\tanβ>30$.

LHC limits on gluinos and squarks in the minimal Dirac gaugino model
狄拉克高吉诺是一个动机良好的MSSM的扩展，导致有趣的现象学后果。与MSSM相比，在LHC中，胶子对的产生被增强，而夸克的产生被抑制，并且衰变特征被更复杂的电荷伴子和中性伴子光谱改变。我们调查如何影响当前的胶子和夸克质量限制运行2的LHC。具体地说，我们通过四个基准模型比较了关于电弱-ino谱的不同假设，特别注意三线性$λ_S$耦合的影响，它引起了大部分bino/U（1）伴随态之间的质量分裂。在其他结果中，我们表明，对于大$λ_S$，额外的$\tildeχ^0_2\to f\bar f \tildeχ^0_1$衰变在一定程度上削弱了重夸克（胶子）情况下对胶子（夸克）的限制。此外，我们比较了在胶子与夸克质量平面的限制，在等价的MSSM方案。
