Using $\tau$ Polarization as a Distinctive SUGRA Signature at LHC

In the minimal SUGRA model the lighter tau slepton is expected to be the second lightest superparticle over a large parameter range at large $\tan\beta$. Consequently one expects a viable SUGRA signal at LHC in the tau lepton channel coming from the decay of these tau sleptons. The model predicts th...

description In the minimal SUGRA model the lighter tau slepton is expected to be the second lightest superparticle over a large parameter range at large $\tan\beta$. Consequently one expects a viable SUGRA signal at LHC in the tau lepton channel coming from the decay of these tau sleptons. The model predicts the polarization of this tau lepton to be +1 to a very good accuracy. We show how this prediction can be tested by looking at the momentum fraction of the tau-jet, carried by the charged prong, in its 1-prong hadronic decay channel.
