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 mesons. We do so in the context of existing experimental…
as four-quark state
Anna Zuzana Dubnickova, Stanislav Dubnicka, Aidos Issadykov +2
We treat the resonance as a four-quark state in the framework of the covariant confining quark model. We study two choices of the interpolating current, either the molecu…
On the choice of heavy baryon currents in the relativistic three-quark model
M. A. Ivanov, J. G. Korner, V. E. Lyubovitskij +2
We test the sensitivity of bottom baryon observables with regard to the choice of the interpolating three-quark currents within the relativistic three-quark model. We have found th…
Strong and Radiative Decays of Heavy Flavored Baryons
M. A. Ivanov, J. G. Korner, V. E. Lyubovitskij +1
We analyze strong one-pion and radiative one-photon decays of heavy flavored baryons within a relativistic three-quark model. Employing the same parameters as were used for the des…
Charm and Bottom Baryon Decays in the Bethe-Salpeter Approach: Heavy to Heavy Semileptonic Transitions
M. A. Ivanov, J. G. Korner, V. E. Lyubovitskij +1
Charm and bottom baryons and mesons are studied within the framework of a relativistically covariant 3D reduction of the Bethe-Salpeter equation. We carry out an analysis of semile…
(Pi+Pi-) Atom in Chiral Perturbation Theory
M. A. Ivanov, V. E. Lyubovitskij, E. Z. Lipartia +1
Hadronic (Pi+Pi-) atom is studied in the relativistic perturbative approach based on the Bethe-Salpeter equation. The general expression for the atom lifetime is derived. Lowest-or…
Exclusive nonleptonic bottom to charm baryon decays including nonfactorizable contributions
M. A. Ivanov, J. G. Korner, V. E. Lyubovitskij +1
Exclusive nonleptonic decays of bottom baryons to charm baryons and pseudoscalar light mesons are analyzed within a relativistic three-quark model. We include factorizing as well a…
Electromagnetic form factors of nucleons in a relativistic three-quark model
M. A. Ivanov, M. P. Locher, V. E. Lyubovitskij
We report the calculation of electromagnetic form factors of nucleons within a relativistic three-quark model with Gaussian shape for the nucleon-quark vertex. The allowed region f…
Semileptonic Decays of Bottom and Charm Baryons within Relativistic Quark Model
M. A. Ivanov, V. E. Lyubovitskij
The results for observables of semileptonic decays of bottom and charm baryons (Isgur-Wise functions, decay rates, distributions, asymmetry parameters) are given within relativisti…
