Analyzing leptonic decays of heavy quarkonia in covariant confined quark model

Stanislav Dubnička, Anna Zuzana Dubničková, Mikhail A. Ivanov +3

The leptonic decay widths of heavy quarkonia are complementary observables to the semileptonic decays of heavy mesons and provide additional insight into the possible lepton flavor…

B meson decays in covariant confined quark model

Stanislav Dubnička, Anna Zuzana Dubničková, Mikhail Alekseevich Ivanov +1

The aim of this text to present the covariant confined quark model (CCQM) and review its applications to the decays of $B$ mesons. We do so in the context of existing experimental…

Definite evidence for physically incomprehensible inequality $σ_{t o t} (e^{+} e^{-} \to n n ˉ) > σ_{t o t} (e^{+} e^{-} \to p p ˉ)$

Stanislav Dubnička, Anna Z. Dubničková

Though the neutron mass is larger than the proton mass and obviously one expects in $e^{+} e^{-}$ annihilation a creation of more $p p ˉ$ pairs in comparison with $n n ˉ$ at the s…

Study of $B_{s} \to ℓ^{+} ℓ^{-} γ$ decays in covariant quark model

Stanislav Dubnička, Anna Z. Dubničková, Mikhail A. Ivanov +3

We study the rare radiative leptonic decays $B_{s} \to ℓ^{+} ℓ^{-} γ$ ( $ℓ = e, μ, τ$ ) within the Standard Model, considering both the structure-dependent amplitude and bremsstrahlung. I…

Erratum: Numerical values of the $f^{F}, f^{D}$ and $f^{S}$ coupling constants in SU(3) invariant Lagrangian of the interaction of the vector-meson nonets with $1/ 2^{+}$ octet baryons [Phys. Rev. C93, 055208 (2016)]

Cyril Adamuščin, Erik Bartoš, Stanislav Dubnička +1

It is clearly demonstrated that numerical values of the $f^{F}, f^{D}$ and $f^{S}$ coupling constants in SU(3) invariant Lagrangian of the interaction of the vector-meson nonets with $1/…
