    • Abstract

       

      We explore the possibility of extracting the weak phase γ from pure tree decays Λb→ Λ(ie687_01) in a model independent way. We find the CP violating phase γ can be determined cleanly without any hadronic uncertainties. Furthermore, these decays are free from the penguin pollution and neither tagging nor time dependent studies are required for the extraction.
