ABSTRACT: In this paper, we give a brief review of the Minimal Supersymmetric Standard Model (MSSM) and “ u from v” Supersymmetric Standard Model ( uv SSM). Then we propose a generalization of uv SSM in order to explain the recent ATLAS, CMS and LHCb results. This “new” uv SSM generalizes the superpotential Wsupport of uv SSM by including two terms that generate a mixing among leptons, gauginos and higgsinos while keeping the charginos and neutralinos masses unchanged. Also, it is potentially interesting for cosmological applications as it displays flat directions of the superpotential and a viable leptogenesis mechanism.
