Abstract

Abstract: The CP conserving Zγγ and ZZγ couplings in the SM and MSSM models at loop level were investigated. For the both models, the coupling parameters h 3 Z, h 3 γ, f 5 γ were estimated for the energy ranges, accessible at the LHC. Extension of the considered energy range up to 14 TeV leads to a possibility to constrain theories by using experimental limits on anomalous couplings from the LHC experiments. It was found that in order to constrain the parameters of the MSSM model, a measurement accuracy of the order of 10 −7 is required.
