Abstract

We present a model independent analysis of $Λ$ baryon polarizations in the $Λ_{b} \to Λ l^{+} l^{-}$ decay. The sensitivity of the averaged $Λ$ polarizations to the new Wilson coefficients is studied. It is observed that there exist certain regions of the new Wilson coefficients where the branching ratio coincides with the standard model prediction, while the $Λ$ baryon polarizations deviate from the standard model results remarkably.
