Can We Identify a Light Neutralino in B-Factories

Abstract

If a light gaugino sector exists, then the lightest supersymmetric particle (LSP) has a chance of being pair-produced in rare B-decays. As a consequence of neutral flavour violation in most supersymmetric models, such decays can occur at the tree-level and reinforce the channels $B⟶K(K^{\ast })+invisible$. We discuss how a study of such decay spectra in B-factories can help us either identify or exclude a light LSP.
