T violation in (Lambda_b -> Lambda l^+ l^-) decay beyond standard model

Abstract

Using the most general, model independent form of effective Hamiltonian, the transverse polarization P_T of Lambda in Lambda_b -> Lambda l^+ l^- decay is studied. It is observed that the averaged <P_T> is very sensitive to the existence of new physics and can attain large values, which can be measured at future colliders.
