Top polarization and New Physics at LHC

I will discuss how top polarization can be utilized to probe new physics in various different top production processes. We find that lab-frame charged lepton distribution from top quark decay can be a useful probe of new physics. We construct various asymmetries sensitive to top polarization and new phsyics. We parametrize new physics in terms of anomalous Wtb couplings and top-chromomagnetic and chromoelectric dipole moments. We find that asymmetries we construct can put stringent constraints on different anomalous couplings.
