Enhancement of CP violation in B$^{\pm}$ --> K$_{i}^{\pm}$ D$^{0}$
Resonance width effects in charged B decays to neutral D mesons and excited kaon states K_i around 1400 MeV are shown to lead to large calculable final state phases. CP asymmetries are defined for any charged B decay to three pseudoscalar mesons involving intermediate overlapping resonance states. A...

description | Resonance width effects in charged B decays to neutral D mesons and excited kaon states K_i around 1400 MeV are shown to lead to large calculable final state phases. CP asymmetries are defined for any charged B decay to three pseudoscalar mesons involving intermediate overlapping resonance states. Asymmetries up to about 10\% are found in B^+\to K^+_i D^0\to (K\pi)^+ D^0. Decay distributions can be used to determine the weak phase \gamma of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. No separation of the contributions from individual resonances is required. |
