Radiative magnetic dipole decays of heavy-light vector mesons into pseudoscalar mesons V -> P\gamma are considered within the relativistic quark model. The light quark is treated completely relativistically, while for the heavy quark the 1/m_Q expansion is used. It is found that relativistic effects result in a significant reduction of decay rates. Comparison with previous predictions and recent experimental data is presented.

  1. Electromagnetic polarizabilities of the triplet hadrons in heavy hadron chiral perturbation theory

    hep-ph 2026-02 unverdicted novelty 7.0 of 10

    Heavy hadron chiral perturbation theory predicts giant electric polarizabilities for D star mesons from near-degenerate pion thresholds and flavor-dependent values for doubly heavy baryons.

  2. Radiative Decays of Vector Mesons with Light-Cone Sum Rules

    hep-ph 2025-11 unverdicted novelty 5.0 of 10

    Light-cone sum rules yield radiative decay widths for ground-state vector mesons that match data where available and exhibit a universal linear dependence on a function A(x) in log coordinates arising from decay-const...

  3. Relativistic effects in $\mbox{M1}$ radiative decays of heavy-light mesons

    hep-ph 2025-07 conditional novelty 5.0 of 10

    A relativistic potential model, with all parameters taken from meson masses, predicts M1 radiative widths for D and D_s mesons and gives a B_s hyperfine splitting close to the new CMS measurement.

  4. Systematic study of light and charm meson M1 radiative transitions

    hep-ph 2025-06 conditional novelty 5.0 of 10

    The paper calculates vector meson magnetic moments and M1 radiative decay widths for light and charm mesons, finding that both models need empirical scale factors to match measured charm decays.
