Using Tau Polarisation for Charged Higgs Boson and SUSY Searches at the LHC

  • Monoranjan Guchait

The т polarisation can be easily measured at the LHC in the 1-prong hadronic т decay channel by measuring what fraction of the т-jet momentum is carried by the charged track. A simple cut requiring this fraction to be τ; 0.8 retains most of the P т=+1 т -jet signal while suppressing the P т=−1 т-jet background and practically eliminating the fake t background. This can be utilised to extract the charged Higgs signal. It can be also utilised to extract the SUSY signal in the stau NLSP region, and in particular the stau co-annihilaton region.
