Unparticle physics effects in (Lambda_b -> Lambda + missing energy) processes

Abstract

We study unparticle physics effects in (Lambda_b -> Lambda + missing energy) decay with polarized ${\Lambda }_b$ and $\Lambda$ baryons. The sensitivity of the branching ratio of this decay and polarizations of (Lambda_b) and (Lambda) baryons on the scale dimension d_U and effective cut-off parameter (Lambda_U) are discussed.
