The cross section values of $J/\psi\ \eta_c$ and $J/\psi\ J/\psi$ production in $e^+e^-$ annihilation are estimated within one-loop approximation near $Z$ pole, as well as at higher energies. Both intermediate bosons, $\gamma$ and $Z$, are taken into

We present theoretical analysis of paired $B_c$ mesons production in $e^+e^-$ annihilation at different energy scales taking into account full next-to-leading order QCD corrections. Both possible electroweak channels are considered: production via vi

In the present work we study production of $J/\psi + \chi_c$ and $J/\psi + J/\psi$ in LHC. The first process is forbidden at the leading order in gluon fusion due to the $C$-parity conservation, and the first non-vanishing contribution is given by th

In the present paper we study the production of $\chi_b + c\bar c$ at the LHC within single parton scattering approach. A special attention payed to the feed-down from $\chi_b$ states to the associated $\Upsilon + c\bar c$ production, which was recen

Inclusive production of $\Upsilon J/\psi$ pair in proton-proton interation at LHCb is considered. This process is forbidden at leading order of perturbation theory, so such channels as double parton scattering, $\chi_b\chi_c$ pair production with sub

The paper is devoted to theoretical consideration of inclusive $\eta_{c,b}$ meson production at LHC. It is shown that existing experimental data on $\eta_c$ meson production at LHCb detector can be described in the framework of NRQCD formalism and co

This paper is devoted to phenomenological study of $\chi_{c,b}$-mesons production in high energy hadronic collisions in the framework of NRQCD. We analyze all available experimental data on $\chi_c$-mesons production and extract non-perturbative NRQC

Inclusive radiative decays $B_c\to\gamma u\bar{d}$ are considered. It is shown that photon emission allows one to bypass the chiral suppression and leads the increase of the branching fraction by about four orders of magnitude. The estimates of exclu

This report is devoted to the analytical calculation of heavy quarkonia production processes in modern experiments such as LHC, B-factories and superB-factories in computer. Theoretical description of heavy quarkonia is based on the factorization the

Hadronic production of $P$-wave charmonium states $\chi_{cJ}$ in hadronic interaction is considered. Using experimental results of CDF and LHCb collaborations we show, that contributions of color-singlet components are dominant. As for color-octet me
