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 λ^{\rm MSSM}_hhh/λ^{\rm SM}_hhh is above 0.97, due to the highly constrained parameter space. While the ratio λ^{\rm NMSSM}_hhh/λ^{\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.
