Effects of CP phases on the Phenomenology of SUSY Particles

We review our recent studies on the effects of CP-violating supersymmetric (SUSY) parameters on the phenomenology of neutralinos, charginos and third generation squarks. The CP-even branching ratios of the squarks show a pronounced dependence on the phases of A_t, A_b, mu and M_1 in a large region of the supersymmetric parameter space, which can be used to get information on these phases. In addition we have studied CP-odd observables, like asymmetries based on triple product correlations. In neutralino and chargino production with subsequent three-body decays these asymmetries can be as large as 20%.Comment: 10 pages, LaTeX, 4 eps figures, uses ws-procs9x6.cls, invited plenary talk presented by A.

Standard Model and Beyond

We first discuss the basic features of electroweak 1-loop corrections in the Standard Model. We also give a short and elementary review on Higgs boson searches, grand unification, supersymmetry and extra dimensions.Comment: 20 pages, LaTeX, 7 eps figures, uses ws-procs9x6.cls, lecture given by A.
