Selected Decays of B&sub(S) Meson in Covariant Confined Quark Model / S.Dubnicka, M.A.Ivanov, [a.o.]. – 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 Bs 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*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
