Sealing the Fate of Higgsino Dark Matter

Abstract

We analyze the LEP constraints from searches for charginos and neutralinos i , taking into account radiative corrections to the relations between their masses and the underlying Higgs-mixing and gaugino-mass parameters ; m 1=2 and the trilinear mass parameter A t. Whilst radiative corrections do not alter the excluded domain in m as a function of m ? m… (More)
