Abstract

The branching fractions and the decay amplitudes of B → J / ψ K* decays are measured in a 29.4 fb-1 data sample collected with the Belle detector at the KEKB electron-positron collider. The decay amplitudes of helicity states of the J / ψ K* system are determined from the full angular distribution of the final state particles in the transversity basis. The branching fractions are measured to be (1.29 ± 0.05 ± 0.13) × 10-3 for neutral mesons and (1.28 ± 0.07 ± 0.14) × 10-3 for charged mesons. The measured longitudinal and transverse (perpendicular to the transversity plane) amplitudes are |A0|2 = 0.62 ± 0.02 ± 0.03 and |A⊥|2 = 0.19 ± 0.02 ± 0.03, respectively. The value of |A⊥|2 shows that the CP even component dominates in the B0 → J/ψ K*0(KSπ0) decay.

N2 - The branching fractions and the decay amplitudes of B → J / ψ K* decays are measured in a 29.4 fb-1 data sample collected with the Belle detector at the KEKB electron-positron collider. The decay amplitudes of helicity states of the J / ψ K* system are determined from the full angular distribution of the final state particles in the transversity basis. The branching fractions are measured to be (1.29 ± 0.05 ± 0.13) × 10-3 for neutral mesons and (1.28 ± 0.07 ± 0.14) × 10-3 for charged mesons. The measured longitudinal and transverse (perpendicular to the transversity plane) amplitudes are |A0|2 = 0.62 ± 0.02 ± 0.03 and |A⊥|2 = 0.19 ± 0.02 ± 0.03, respectively. The value of |A⊥|2 shows that the CP even component dominates in the B0 → J/ψ K*0(KSπ0) decay.
