Search for squarks and gluinos in final states with hadronically decaying τ -leptons, jets, and missing transverse momentum using pp collisions at s

Abstract: 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 √ 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 expec… Show more

“…In short, the simultaneous conditions of a 1.1 to 1.2 TeV Higgsino, a 125 GeV Higgs, and correct electroweak breaking provide a discrete set of values for the three parameters (q R , q H , 1/R) -this is a non-trivial statement since it was not guaranteed a priori that a viable solution would exist. Moreover, for the q H , q R , and 1/R values consistent with these conditions, we find solutions that have spectra that are completely compatible with current LHC superpartner and direct dark matter searches [18,19]. The net result is a model with three free parameters (q R , q H , 1/R) that is able to reproduce the correct electroweak breaking, the correct Higgs mass, provide a viable DM candidate, and passes all experimental bounds.…”

“…A majority of direct searches at the LHC have excluded stops and gluinos below the TeV scale (Refs. [170][171][172][173][174][175][176][177][178] show some such limits in various supersymmetric interpretations). This more or less nullifies the prospect of observing these particles unless the luminosity is enhanced significantly.…”

“…An inclusive search for squarks and gluinos produced via the strong interaction in events with jets, at least one hadronically decaying to τ-lepton, and large missing transverse momentum is performed by the ATLAS Collaboration [4]. Two SUSY models are considered: a simplified model [5][6][7] of gluino pair production and a model of gauge-mediated SUSY breaking (GMSB) [8][9][10], see Figure 1.…”
