Effects of Flavor Dependence on Weak Decays of J / ψ and ϒ

Abstract

We carry out a detailed analysis of effects of flavor dependence of average transverse quark momentum inside a meson on J / ψ → P and ϒ → B c transition form factors and two-body weak hadronic decays of J / ψ and ϒ employing the factorization scheme. We predict the branching ratios of semileptonic and nonleptonic weak decays of J / ψ and ϒ mesons in Cabibbo-angle-enhanced and Cabibbo-angle-suppressed modes.
