Violation of SUSY equivalence in triple gauge boson and gaugino couplings

Supersymmetry implies that the trilinear couplings between gauge bosons and gauginos are equal to all orders. However if SUSY is broken and some of the superpartners have large SUSY breaking masses then they can induce non-decoupling deviations in this relation through radiative corrections. In this work we show that the deviation in the ratio g̃wχ̃γ̃ gγww from unity can be around 2.3% (3.3%) in heavy QCD models (2-1 models) for a point in the gaugino region. Precision measurement of triple gaugino couplings at future high energy colliders can therefore probe such violations and the existence of heavy superparticles in the multi Tev region which are otherwise inaccessible.
