We give the detailed analysis of effects of flavor dependence of average transverse quark momentum inside a meson on J/psi --> P and \Upsilon --> Bc transition form factors and two-body weak hadronic decays of J/psi and \Upsilon employing the factorization scheme. We predict the branching ratios of semileptonic and nonleptonic weak decays of J/psi and \Upsilon mesons in Cabibbo-angle-enhanced and Cabibbo-angle-suppressed modes.

  1. The $\Upsilon(nS) \to B_{(c)}$ transition form factors and their applications to semileptonic and nonleptonic weak decays

    hep-ph 2026-07 conditional novelty 5.0 of 10

    The authors use the covariant light-front quark model to predict branching ratios of order 10^-9 to 10^-15 for weak Υ(1S-4S) → B/B_c decays, with Υ(3S) → B_c ℓν the largest.

  2. Polarization observables in semileptonic $V\to P$ decays of quarkonia

    hep-ph 2025-06 conditional novelty 5.0 of 10

    Using the helicity amplitude method, the authors derive the angular distribution for vector-to-pseudoscalar semileptonic decays and predict polarization observables for J/psi and Upsilon(1S) channels.
