We report on recebt theoretical results on 3-loop anomalous dimensions and massless ans massive Wilson coefficients in the unpolarized and polarized case.
We study the prompt single and double J/ψ hadroproduction in the Improved Color Evaporation Model using the Parton Reggeization Approach. We make calculations in a single manner to described the experimental data for prompt J/ψ transverse momentum spectra from the energy of $\sqrt{s}=19$ GeV up to modern energy of the LHC, $\sqrt{s}=13$ TeV. The numerical calculations are doing using...
Quarkonium has been used as an important probe of the quark-gluon plasma in heavy ion collisions. With more precise experimental measurements of quarkonium production conducted at RHIC and LHC, we are able to learn in a more quantitative way how quarkonium interacts with the hot medium. In this talk, I will review the framework of coupled Boltzmann equations to describe quarkonium production...
