If Supersymmetry (SUSY) exists in nature, the LHC might find first evidence for it within the next few years. After new physics phenomena are discovered, there will be many proposed explanations including supersymmetric models that will be consistent with the initial discovery. It is critical to identify observables that can provide direct evidence for an underlying supersymmetric dynamics. SUSY predicts the gauge couplings and the corresponding Yukawa couplings between fermions, sfermions and gauginos to be equal. We show that monojets at LHC provide a test of the U(1) and the SU(2) coupling relations. We investigate the regions of the MSSM parameter space, where such a test is possible. We found that scenarios with a wino-like lightest supersymmetric particle are the most promising ones due to an enhanced monojet cross section.
