Selected Decays of B&sub(S) Meson in Covariant Confined Quark Model / S.Dubnicka, A.Z.Dubnickova, M.A.Ivanov, A.Liptaj. – Text: electronic // The European Physical Journal A. – 2026. – Vol. 62, No. 5. – P. 106. – URL: https://doi.org/10.1140/epja/s10050-026-01868-7. – Bibliogr.: 66.
We present a study of various B&sub(s) meson decays, including hadronic and semileptonic final states with different spins and diagram topologies. The covariant confined quark model is employed to describe hadronic effects, and our analysis serves as a broad test of the current understanding of the underlying dynamics within the Standard Model. The level of agreement with experimental data varies across channels: it is good for the semileptonic decays B*0&sub(s) → D*-&sub(s) μ*+ν&sub(μ) and B*0&sub(s) → K*-μ*+ν&sub(μ); acceptable for the hadronic modes B*-0&sub(s) → D*-&sub(s)D*+ and B*0&sub(s) → K*-π*+; marginal for B*0&sub(s) → D*-&sub(s)π*+, B*0&sub(s) → D*-&sub(s)ρ*+, and B*0&sub(s) → φ J/ψ; and significantly discrepant for B*0&sub(s) → φ D^-&sup(0) and B*0&sub(s) → φ η&sub(c). We argue that the observed inconsistencies may arise from the breakdown of naive factorization and unaccounted longdistance effects. In particular, the channels B*0&sub(s) → D*-&sub(s)π*+ and B*0&sub(s) → D*-&sub(s)ρ*+ are theoretically among the cleanest nonleptonic decays, yet they exhibit persistent discrepancies also reported by other theoretical groups.
