Semileptonic decays of the bottom-charm hadrons
Mikhail A. Ivanov
We present the results of a study of the semileptonic decays of the -meson and the lowest lying doubly heavy baryons using the relativistic quark model. We do not employ a hea…
Heavy-Meson Observables via Dyson-Schwinger Equations
M. A. Ivanov, Yu. L. Kalinovsky, C. D. Roberts
We summarise a Dyson-Schwinger-equation-based calculation of an extensive range of light- and heavy-meson observables, characterised by heavy-meson leptonic decays, semileptonic he…
Dyson-Schwinger Equation Approach to the QCD Deconfinement Transition and J/Psi Dissociation
D. B. Blaschke, G. R. G. Burau, M. A. Ivanov +2
We consider an extension of the finite-temperature Dyson-Schwinger equation (DSE) approach to heavy mesons and quarkonia and apply it to calculate the cross section for the J/Psi b…
Decay Constants and Semileptonic Form Factors of Pseudoscalar Mesons
M. A. Ivanov, P. Santorelli
A relativistic constituent quark model is adopted to give an unified description of the leptonic and semileptonic decays of pseudoscalar mesons (π, K, D, D_s, B, B_s). The calculat…
Theory of the pi+ pi- atom
M. A. Ivanov, V. E. Lyubovitskij, E. Z. Lipartia +1
The relativistic perturbative approach based on the Bethe-Salpeter (BS) equation is developed for the study of the characteristics of the hadronic pi+ pi- atom. The general express…
pi+pi- Atom in Chiral Theories
M. A. Ivanov, V. E. Lyubovitskij, E. Z. Lipartia +1
We review the existing theoretical approaches to the study of the observables of hadronic atoms. In the relativistic perturbative approach based on the Bethe-Salpeter equation and…
