Using Tau Polarization for Charged Higgs Boson and SUSY Searches at LHC / Guchait, Monoranjan (Tata Inst.) ; Roy, D.P. (Tata Inst.)
The $\tau$ polarization can be easily measured at LHC in the 1-prong hadronic $\tau$ decay channel by measuring what fraction of the $\tau$-jet momentum is carried by the charged track. A simple cut requiring this fraction to be >0.8 retains most of the polarization of $\tau=$+1 $\tau$-jet signal while suppressing the polarization of $\tau=$-1 $\tau$-jet background and practically eliminating the fake $\tau$ background.

We report on a plan to establish a "Dictionary of LHC Signatures", an initiative that started at the WHEPPX workshop in January 2008. This study aims towards the strategy on distinguishing of 3 classes of dark matter motivated scenarios such as R-parity conserved supersymmetry, Little Higgs models with T-parity conservation and Universal Extra Dimensions with KK-parity for generic cases of their realization in wide range of the model space.

There are many possibilities for new physics beyond the Standard Model that feature non-standard Higgs sectors. These may introduce new sources of CP violation, and there may be mixing between multiple Higgs bosons or other new scalar bosons. [...]

Probing the CP-violating light neutral Higgs in the charged Higgs decay at the LHC / Ghosh, Dilip Kumar (Wurzburg U.) ; Godbole, R.M. (Bangalore, Indian Inst. Sci.) ; Roy, D.P. (Tata Inst. ; CERN)
The CP-violating MSSM allows existence of a light neutral Higgs boson ($M_{H_1} \lapp 50$ GeV) in the CPX scenario in the low $\tan \beta (\lapp 5)$ region, which could have escaped the LEP searches due to a strongly suppressed $H_1 Z Z$ coupling. This parameter space corresponds to a relatively light $H^\pm$ ($M_{H^\pm} < M_t$), which is predicted to decay dominantly into the $W H_1$ channel. [...]

Using Tau Polarization to Discriminate between SUSY Models and Determine SUSY Parameters at ILC / Godbole, R.M. (Bangalore, Indian Inst. Sci.) ; Guchait, Monoranjan (Tata Inst. ; CERN) ; Roy, D.P. (Tata Inst. ; CERN)
In many SUSY models the first SUSY signal in the proposed International Linear Collider is expected to come from the pair production of $\tilde\tau_1$, followed by its decay into $\tau$+LSP. We study a simple and robust method of measuring the polarization of this $\tau$ in its 1-prong hadronic decay channel,and show how it can be used to discriminate between SUSY models and to determine SUSY parameters..

The Charged Higgs Boson Search at LHC / Roy, D P (Tata Inst.)
This review starts with a brief introduction to the charged Higgs boson $(H^\pm)$ in the Minimal Supersymmetric Standard Model (MSSM). It then discusses the prospects of a relatively light $H^\pm$ boson search via top quark decay and finally a heavy $H^\pm$ boson search at LHC. [...]
