Description
Summary:A bstract As a sequel to our recent paper we examine the phenomenology of the full electroweakino sector of the pMSSM without invoking the ad hoc but often employed assumption that the heavier ones are decoupled. We showcase the importance of the heavier electroweakinos using several generic models with different hierarchies among the slepton and electroweakino masses. We obtain constraints from the LHC data which are stronger than that for decoupled heavier electroweakinos. Using the additional constraints from the observed dark matter relic density of the universe and the precisely measured anomalous magnetic moment of the muon we determine the allowed parameter space. We then show that novel signatures with m > 3 may be observed before the next long shut down of the LHC.
