Description
Due to supersymmetry, the quark-squark-gluino Yukawa coupling is constrained to be
equal to the corresponding quark-quark-gluon QCD gauge coupling. Based on earlier
investigations of like-sign dilepton final states, it is shown how information about
this coupling can be extracted from an analysis of squark and gluino production
processes at LHC. The method is refined to be maximally independent of model
assumptions and of data ouside of LHC. Using simulations of the relevant processes,
estimates for the expected precision are given.
