Heavy Higgs as a portal to the supersymmetric electroweak sector

Abstract: The electroweak sector of the Minimal Supersymmetric Standard Model (MSSM) -neutralinos, charginos and sleptons -remains relatively weakly constrained at the LHC due in part to the small production cross sections of these particles. In this paper, we study the prospects of searching for decays of heavy Higgs bosons into these superpartners at the high luminosity LHC. In addition to the kinematic handles offered by the presence of a resonant particle in the production chain, heavy Higgs decays can be the domina… Show more

“…Ref. [153] for a thorough analysis on the sensitivity in a class of benchmark scenarios. The electroweakino spectrum is fixed at tree-level by the choice of μ, M 1 , M 2 and the value of tan β and exhibits a strong wino-Higgsino mixing in both the neutralino and chargino sector.…”

“…On the other hand, their branching ratio into τ -pairs is still ∼4%, which makes them potentially detectable in this channel with more luminosity. Further, their decays into charginos/neutralinos as well as cascade decays into additional Higgs bosons may provide complimentary search handles at the LHC [63][64][65][66][67][68][69].…”
