Project objective

Research objectives and content The research objective of the proposecl project is the study of the phenomenological implications of extensions of supersymmetric models at the col- lider machines. The moclels I will study include the minimal supersymmetric standard model with an aclditional gauge singlet models with an extra U(1) and superstring-derived models. I will study both the direct and indirect evidences of such models. As indirect evidences I will focus on the precise electroweak measurcments at LEP and SLC. I will compute the radiative corrections within these models and thell I ill compare ttlC electro eak data with ttle theoretical predictions studying how to discrilllinate betweell the arious mo(lels. For the direct searches at LEP 2 the Tevatron and LHC I will compute the cross sec- tion of production of the supersymmetric particles within the above models. Training content (objective benefit and expected impact) With the proposecl project I expect to acquire a lot of experience and a very good knowledge on superstring-deri ed models SIlSy models with e;tra U(1) and/or with extra gauge singlets. I t)elie e that thc collaboratioll with the re- search group in Paris will be a ery goocl opportunity to increase my knowledge o n this subject. Links with industry / industrial relevance (2 )
