Probing the sgeneration spectrum in chargino decays

Abstract

Some mechanisms of supersymmetry breaking result in splitting of the third generation sfermions from the other sfermions. We show that the three-body decay branching ratio of the lighter chargino gives a sensitive probe of the sfermion mass spectrum if the chargino has a large gaugino component.
