Yet another way to measure gamma

We show that the CKM phase 2 beta + gamma can be extracted from measurement of the time dependent rates in the decays (B) over bar (0) --> D-(*M-)+/-( -/+) and B-0 --> D-(*M-)+/-(+/-), where M = a(0), pi (1300), b(1), a(2), pi (2), rho (3). These channels have a large asymmetry between decays of (B) over bar (0) and B-0 into the same final state. Even though the branching r atios are small, their sensitivity to gamma can be competitive with decays into D-(*()) and (pi, rho, a(1)). (C) 2001 Elsevier Science B.V. All rights reserved.
