Description

We propose an effective description of squark interactions with charginos/neutralinos. We recompute the strong corrections to squark partial decay widths, and compare the full one-loop computation with the effective description. The effective description includes the effective Yukawa couplings, and another logarithmic term which encodes the supersymmetry-breaking. The proposed effective couplings reproduce correctly the radiative-corrected partial decay widths of the squark decays into charginos and neutralinos in all relevant regions of the parameter space.
