Abstract

A multitude of searches have already been performed by the ATLAS and CMS collaborations at the LHC to probe the heavy Higgses of the minimal supersymmetric Standard Model (MSSM) through their decay to the Standard Model particles. In this paper, we study the decay of the MSSM heavy Higgses into neutralino and chargino pairs and estimate the maximum possible branching ratios for these ``ino'' modes being consistent with the present LHC data. After performing a random scan of the relevant electroweakino parameters, we impose the SM 125 GeV Higgs constraints and low-energy flavor data. We choose a few representative benchmark points satisfying all the above-mentioned constraints as well as the current bounds on heavy Higgses and electroweakinos from the LHC Run-I and Run-II data. We then perform a detailed collider simulation, including fast detector effects, and analyze all the potential SM backgrounds in order to estimate the discovery reach of these heavy Higgses at the LHC. We restrict ourselves within the leptonic cascade decay modes of these heavy Higgses and study the mono-X + is not an element of(T) (X = W, Z) and trilepton + is not an element of(T) signatures in the context of a high-luminosity run of the 14 TeV LHC.
