abstract

We estimate the strong coupling constants of charmed and bottom mesons $ D_{(s)}^* $, $ D_{(s)1} $, $ B_{(s)}^* $, and $ B_{(s)1} $ with light vector mesons $ \rho $, $ \omega $, $ K^* $, and $ \phi $ within the framework of light-cone QCD sum rules. We compare our estimations to the ones predicted by other approaches.

  1. Dispersive Analysis of $D$- and $B$-Meson Form Factors with Chiral and Heavy-Quark Constraints

    hep-ph 2026-03 conditional novelty 7.0 of 10

    The isovector D/D*/B/B* electromagnetic form factors are reconstructed dispersively with ππ rescattering, yielding ρ(770) coupling constants from pole residues.

  2. Emergence of the exotic bottomoniumlike state $Y(10650)$ and support from Belle and Belle II data

    hep-ph 2025-05 conditional novelty 6.0 of 10

    A coupled-channel meson-exchange calculation predicts P-wave B(*)Bbar(*) states Y(10600) and Y(10650), with Y(10650) matching threshold anomalies in Belle and Belle II data.
