Abstract

The sensitivity of the CKM angle γ\gamma in Λb0DΛ\Lambda_b^0 \to D \Lambda decays has been studied using the decay parameter α\alpha as an observable in addition to the decay rate asymmetry. Feasibility studies show that adding this observable improves the sensitivity on γ\gamma by up to 60\% and makes the decays one of the most promising places to measure angle γ\gamma and to search for C ⁣PC\!P violation in bb-baryon decays.
