Exclusive hadronicBdecays to charm and charmonium final states

Inclusive decays ofBmesons to charmonium

“…The inclusive studies reported here are complementary to CLEO-II measurements of exclusive B decays to charmonium which have recently been reported [14,15].…”

Measurement of the Decay Amplitudes and Branching Fractions ofB→J/ψK*andJessop1, Lingel2, Marsiske3 et al. 1997Phys. Rev. Lett.Self Cite

“…The J/ψ is reconstructed in its leptonic decay modes to e + e − and µ + µ − . The measurements presented here supersede previous CLEO II results [8], which are based on a subset of the data used for this analysis.…”

“…There might be a contribution from non-resonant B → J/ψ Kπ decays in the K * signal region, though neither the previous CLEO measurement [8] nor CDF [9] found events in the K * mass sidebands. However, examining the Kπ invariant mass spectrum (Fig.…”

“…It has been noted [5,6], that form factor models cannot simultaneously explain the earlier experimental data for these two quantities. The high values of Γ L /Γ measured by ARGUS [7] and CLEO II [8], with low statistics, are not consistent with factorization and the measured value of R. The CDF collaboration has measured a lower value of Γ L /Γ [9]. Additional information about the validity of factorization can be obtained by a measurement of the decay amplitude phases, since any non-trivial phase differences indicate final state interactions and the breakdown of factorization [10].…”

Annihilation, Rescattering, andCPAsymmetries inBMeson Decays

“…The processes B 0 → π + D − and B 0 → π 0D0 are conventionally given by "colorallowed" and "color-suppressed" amplitudes,T ∝ a 1 andC ∝ a 2 , respectively, which are determined experimentally, a 2 /a 1 ≈ 0.2 [13]. When calculated in the naïve factorization approximation [14], neglecting rescattering effects, both amplitudes are real.…”
