We calculate the amplitudes involved in the heavy baryon nonleptonic decay Λb → ΛJ/ψ using perturbative QCD factorization theorem, which are expressed as convolutions of hard b quark decay amplitudes with the Λb baryon, Λ baryon and J/ψ meson distribution amplitudes. It is found that nonfactorizable contributions dominate over factorizable ones. Employing the distribution amplitudes determined in our previous works, we derive the branching ratio B(Λb → ΛJ/ψ) = (1.65 ~ 5.27) × 10-4 in agreement with data. We predict an asymmetry parameter α = -0.17 ~ -0.14 associated with the anisotropic angular distribution of the Λ baryons produced in polarized Λb baryon decays.

Using Data

Using data collected by FOCUS, we present a preliminary measurement for the vector meson semileptonic branching ratio [Formula: see text]. Using a sample of 397 ± 42 and 11, 811 ± 151 D+ → ρ0μ+ν and [Formula: see text] events, respectively, we find [Formula: see text].
