Search for low-Mass Higgs states @ BaBar

Abstract

Several types of new-physics models predict the existence of light dark matter candidates and low-mass Higgs states. Previous \babar searches for invisible light-Higgs decays have excluded large regions of model parameter space. We present searches for a dark-sector Higgs produced in association with a dark gauge boson and searches for a light Higgs in ${\rm Y}(nS)$ decays.
