Using Tau Polarization to probe the Stau Co-annihilation Region of mSUGRA Model at LHC

R. M. Godbole, Monoranjan Guchait, D. P. Roy

The mSUGRA model predicts the polarization of the tau coming from the stau to bino decay in the co-annihilation region to be +1. This can be exploited to extract this soft tau sign…
