Exotic SUSY scenarios

Abstract

In this talk I discuss some scenarios which involve small extensions of the ideas usually considered in the Minimal Supersymmetric Standard Model (MSSM). I present results of a study of the implication of nonuniversal gaugino masses (NGM) for the invisible decays of the lightest scalar and the correlation of the same with the relic density of the lightest supersymmetric particle (LSP) in the Universe. Further I discuss SUSY with R_p. Decay of χ₁^~0in case of dominant R_p and L, trilinear λ and λ'c couplings and also that of χ₁^~0, χ₁^~+, caused by the bilinear R_p, L couplings are discussed. The effect of the latter for the trilepton signal at the Tevatron is presented. I end with a discussion of signals of Heavy Majorana Neutrinos (HMN) at the LHC.
