Contribution of hadronic light-by-light scattering to the hyperfine structure of muonium

V. I. Korobov, A. V. Eskin, A. P. Martynenko +1

The contribution of hadronic scattering of light-by-light to the hyperfine structure of muonium is calculated using experimental data on the transition form factors of two photons…

Gliding down the QCD transition line, from $N_{f} = 2$ till the onset of conformality

A. Yu. Kotov, M. P. Lombardo, A. Trunin

We review the hot QCD transition with varying number of flavors, from two till the onset of the conformal window. We discuss the universality class for $N_{f} = 2$ , along the critical…

Higgs boson decay to the pair of S- and P-wave $B_{c}$ mesons

R. N. Faustov, F. A. Martynenko, A. P. Martynenko

We investigate the rare production of the pair of $S -$ and $P -$ wave $B_{c}$ -meson in the Higgs boson decay in the perturbative Standard Model and relativistic quark model. Relativis…

Analytic approach to calculations of mass spectra and decay constants of heavy-light quarkonia in the framework of Bethe-Salpeter equation

Eshete Gebrehana, Shashank Bhatnagar, Hluf Negash

This work is an extension of the work in \cite{bhatnagar18} to ground and excited states of $0^{++}, 0^{-+}$ , and $1^{--}$ of heavy-light ($c\overline{u}, c\overline{s}, b\overline…

Double charmonium productions in electron-positron annihilation using Bethe-Salpeter approach

Hluf Negash, Shashank Bhatnagar

We calculate the double charmonium production cross section within the framework of $4 \times 4$ Bethe-Salpeter Equation in the electron-positron annihilation, at center of mass ene…
