Description
We study a supersymmetric scenario where the lighter tau-sneutrino is the lightest
supersymmetric particle, while the lighter stau-state is the next lightest. Such a
scenario can be motivated within the framework of minimal supergravity, with just the
addition of a right-chiral neutrino superfield. Such a spectrum leads to rather
unusual signals of supersymmetry, showing stable tracks of the stau in the muon
chambers. We study the event characteristics of the long-lived staus and demonstrate
that the stau tracks can be distinguished from the muonic ones through proper
kinematic cuts which also enable one to remove all standard model backgrounds.
