Abstract

We have measured the branching fractions for the exclusive decay modes B→χ_c1(2)K(K*) using a 140 fb^-1 data sample collected by the Belle detector at the KEKB asymmetric-energy e ⁺e^- collider. The measured branching fractions for B ⁺→χ_c1K⁺, B⁰→χ _c1K⁰, B⁰→χ_c1K* ⁰ and B⁺→χ_c1K*⁺ decay modes are (4.5±0.2±0.5)×10^-4, (3.5±0.3±0.5)×10^-4, (3.1±0.3±0.7) ×10^-4 and (4.1±0.6±0.9)×10^-4, respectively, where the first error is statistical and the second error is systematic. We do not observe statistically significant signals for the B→χ_c2K(K*) decay modes and set upper limits at the 90% confidence level. We also study the helicity distribution for B→χ_c1K* decay mode and show that the longitudinal polarization component is dominant.

The measured branching fractions for B +→χc1K+, B0→χ c1K0, B0→χc1K* 0 and B+→χc1K*+ decay modes are (4.5±0.2±0.5)×10-4, (3.5±0.3±0.5)×10-4, (3.1±0.3±0.7) ×10-4 and (4.1±0.6±0.9)×10-4, respectively, where the first error is statistical and the second error is systematic. We do not observe statistically significant signals for the B→χc2K(K*) decay modes and set upper limits at the 90% confidence level. We also study the helicity distribution for B→χc1K* decay mode and show that the longitudinal polarization component is dominant.
