Long-lived superpartners in the Constrained MSSM

Abstract

We have considered the parameter space of the Constrained Minimal Supersymmetric Standard Model (CMSSM) and have shown the existence of the certain regions where long-lived charged superparticles exist. This takes place in the co-annihilation region (staus), the region with large negative trilinear scalar coupling A (stops), and the focus-point region (charginos). The phenomenology of the long-lived superparticles is briefly discussed.
