hhh Coupling in SUSY models after LHC run I

High Energy Physics - Phenomenology 2015-04-30 v1

Abstract

We examine the Higgs triple coupling in MSSM and NMSSM under current constraints, which include the LHC measurements, Higgs data, B physics, electroweak precision observables, relic density and so on. The ratio λhhhMSSM/λhhhSM\lambda^{\rm MSSM}_{hhh}/\lambda^{\rm SM}_{hhh} is above 0.97, due to the highly constrained parameter space. While the ratio λhhhNMSSM/λhhhSM\lambda^{\rm NMSSM}_{hhh}/\lambda^{\rm SM}_{hhh} can reach 0.1 under current constraints. The precise measurement in future collider will give a tighter constraint to the Higgs triple coupling in MSSM and NMSSM.
