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…

Decays $B \to D_{(s)}^{(*)} h$ ( $h = π, ρ$ ) in confined covariant quark model

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

Decay processes $B \to D_{(s)}^{(*)} h$ ( $h = π, ρ$ ) are studied in the framework of the confined covariant quark model using the naïve factorization assum…

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…

Prediction of neutron electromagnetic form factors behaviors just by the proton electromagnetic form factors data

Anna Z. Dubničková, Stanislav Dubnička

It is demonstrated how the neutron electromagnetic form factors behaviors in the whole region of their definition can be predicted theoretically just by using the proton form facto…

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/…
