CP violation in the partial width asymmetries for B-→π+π-K- and B-→K+K-K- decays -: art. no. 034033

We investigate the possibility of observing CP asymmetries in partial widths for the decays B--->pi(+)pi(-)K(-) and B--->K+K-K- produced by the interference of the nonresonant decay amplitude with resonant amplitudes. The resonant states that subsequently decay into pi(+)pi(-) and K+K- or K(-)pi(+) are charmonium c $$($) over barc states with J(P)=0(+),1(-),1(+) or the phi(1020) meson. We find that the largest partial width asymmetry comes from the chi(c0) resonance, while the resonance psi(2S) gives a partial width asymmetry of the order 10%.
