Abstract
We analyze the partial rate asymmetry in B+/- --> P (P) over bar pi(+/-) de cays (P = pi(+), K+, pi(0), eta) which results from the interference of the nonresonant decay amplitude and the resonant amplitude for B+/- --> chi(c0 )pi(+/-) followed by the decay X-c0 --> P (P) over bar. The CP violating ph ase gamma can be extracted from the measured asymmetry. We find that the pa rtial rate asymmetry for B+(/-) --> pi(+)pi(-)pi(+/-) is 0.33 sin gamma, wh ile for B+/- -> K+ K- pi(+/-) it amounts 0.45 sin gamma.
