Abstract

In the minimal supersymmetric standard model (MSSM), we study the light Higgs boson radiation off a light-chargino pair in the process e+e−h1+1− at linear colliders with s=500Gev GeV. We analyze cross sections in the regions of the MSSM parameter space where the process e+e−h1+1− cannot proceed via on-shell production and subsequent decay of either heavier charginos or the pseudoscalar Higgs boson A. Cross sections up to a few fb are allowed, according to present experimental limits on the Higgs boson, chargino and sneutrino masses. We also show how a measurement of the e+e−h1+1− production rate could provide a determination of the Higgs boson couplings to charginos.
