Using tau polarization to probe the stau co-annihilation region of the minimal supergravity model at the LHC

Using tau polarization to probe the stau co-annihilation region of the minimal supergravity model at the LHC

The minimal supergravity 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 signal at LHC and also to measure the tiny mass differences between the stau and the bino …
