Electroweakino constraints from LHC data

Abstract

We investigate the sensitivity of existing LHC searches to the charginos and neutralinos of the MSSM when all the other superpartners are decoupled. In this limit, the underlying parameter space reduces to a simple four-dimensional set $\{M_1,M_2,\mu ,\tan \beta \}$. We examine the constraints placed on this parameter space by a broad range of LHC searches taking into account the full set of relevant production and decay channels. We find that the exclusions implied by these searches exceed existing limits from LEP only for smaller values of the Bino mass $M_1\lesssim 150$ GeV. Our results have implications for MSSM dark matter and electroweak baryogenesis.
