Phys. Rev. Lett. 74, 4984–4987 (1995)Large CP Asymmetries in B±→ηc(χc0)π± from the ηc(χc0) WidthReceived 14 February 1995; published in the issue dated 19 June 1995 We study CP asymmetries in B±→hπ± decays, where the hadronic states h = ρρ,KK̅ π,π+π-K+K-, etc., and h = π+π-,K+K-,2(π+π-), etc., are taken on the resonances ηc and χc0, respectively. The relatively large ηc and χc0 decay widths, of about 10–15 MeV, provide the necessary absorptive phase in the interference between the resonance (going through b→cc̅ d) and the background (through b→uu̅ d) contributions to the amplitude. Large asymmetries of order 10% or more are likely in some modes. © 1995 The American Physical Society URL:
