Long-lived triplinos and displaced lepton signals at the LHC

Abstract

We explore the possibility of having superpartners of triplet Higgs bosons, named as 'triplinos'. They form a part of light neutralinos and charginos in a Y=0Y=0 extended supersymmetric Standard Model. For this model such electroweakinos do not have direct couplings to the Standard Model fermions. On top of that, due to very compressed spectrum for lighter neutralinos and charginos, their decay products coming from three body decays are very soft and thus can evade the current collider bounds. These decays are particularly interesting since they give rise to displaced leptonic signatures. We categorise the parameter space, while exploring different displaced decay possibilities. A PYTHIA based simulation has been performed to find out the displaced charged lepton, jet and bb-jet final states at the LHC with center of mass energy of 14 TeV.
