abstract

We study the exclusive semileptonic decays $\Upsilon(1S)\to B_{(c)}\ell\bar{\nu}_\ell$, where $\ell = e,\mu,\tau$. The relevant hadronic form factors are calculated using the Covariant Confined Quark Model developed previously by our group. We predict the branching fractions $\mathcal{B}(\Upsilon(1S)\to B_{(c)}\ell\bar{\nu}_\ell)$ to be of the order of $10^{-13}$ and $10^{-10}$ for the case of $B$ and $B_c$, respectively. Our predictions agree well with other theoretical calculations. We also consider the effects of possible New Physics in the case of $\Upsilon(1S)\to B_c\tau\bar{\nu}_\tau$. We show that the branching fraction of this decay can be enhanced by an order of magnitude using constraints from the $B\to D^{(*)}\ell\bar{\nu}_\ell$ and $B_c\to J/\psi\ell \bar{\nu}_\ell$ experimental data.

  1. Probing the ATOMKI X17 vector boson using Dalitz decays $V\to Pe^+e^-$

    hep-ph 2025-06 conditional novelty 6.0 of 10

    In a quark-model calculation, X17 contributions to D*, B*, and J/psi Dalitz decays are too small to explain the BESIII D*0 e+e- excess unless quark couplings are far outside ATOMKI-favored ranges.

  2. 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.

  3. 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.
