Measurement of the ratio B(B-->(DK-)-K-*0)/B(B--> D-*0 pi(-)) and of the CP asymmetry of B-->(DCP+K)-K-*0- decays

Abstract:

We study the decays B- → D*0π - and B-→ D*0K-, where the D*0 decays into D0π0, with the D0 reconstructed in the CP-even (CP+) eigenstates K-K + and π-π+ and in the (non-CP) channels K-π+, K -π+π+π-, and K -π+π0. Using a sample of about 123 × 106 BB̄ pairs, we measure the ratios of decay rates R*non-CP ≡ B(B- → D* non-CP0K-)/B(B- → D*non-CP0π-) = 0.086 ± 0.0040(stat)-0.0031+0.0042(syst), and provide the first measurements of R*CP+ ≡ B(B- → D*CP+0K-)/B(B- → D*CP+0π-) = 0.0086 ± 0.021(stat) ± 0....
