Measurements of Direct CP Violating Asymmetries in Charmless Decays of Strange Bottom Mesons and Bottom Baryons.

Abstract

We report measurements of direct CP？violating asymmetries in charmless decays of neutral bot- tom hadrons to pairs of charged hadrons with the upgraded Collider Detector at the Fermilab Tevatron. Using a data sample corresponding to 1 fb?1 of integrated luminosity, we obtain the first measurements of direct CP violation in bottom strange mesons,
