Yet another way to measure /γ

Abstract We show that the CKM phase 2 β + γ can be extracted from measurement of the time dependent rates in the decays B 0 →D (∗)± M ∓ and B 0 →D (∗)± M ∓ , where M = a 0 , π (1300), b 1 , a 2 , π 2 , ρ 3 . These channels have a large asymmetry between decays of B 0 and B 0 into the same final state. Even though the branching ratios are small, their sensitivity to γ can be competitive with decays into D (∗) and ( π , ρ , a 1 ).
