Description
The opposite states of the $τ$ polarization resulting from the charged Higgs boson and the $W$ boson decays can be exploited to enhance the $H^\pm$ signal in the inclusive 1-prong hadronic decay channel of $τ$. We suggest practical methods of sharpening up the $H^\pm$ signature in the top quark decay at LHC using this idea. As a result one can carry on the charged Higgs boson search to within $\sim 20 GeV$ of the parent top quark mass over the full parameter space of the MSSM.
