Two-loop integrals for CP-even heavy quarkonium production and decays: elliptic sectors
Journal of High Energy Physics, 2018 By employing the differential equations, we compute analytically the elliptic sectors of two-loop master integrals appearing in the NNLO QCD corrections to CP-even\ heavy quarkonium exclusive production and decays, which turns out to be the last and ...

Double Charmonium Productions in Electron‐Positron Annihilation Using Bethe‐Salpeter Approach
Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 We calculate the double charmonium production cross‐section within the framework of 4 × 4 Bethe‐Salpeter Equation in the electron‐positron annihilation, at center of mass energy s=10.6GeV, that proceeds through the exchange of a single virtual photon.

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019 In this paper, quarkonium dissociation is investigated in an anisotropic plasma in the hot and dense media. For that purpose, the multidimensional Schrödinger equation is solved analytically by Nikiforov‐Uvarov (NU) method for the real part of the potential in an anisotropic medium. The binding energy and dissociation temperature are calculated.

QUARKONIUM AT FINITE TEMPERATURE [PDF]
, 2010 We discuss properties of heavy quarkonium states at high temperatures based on lattice QCD and potential models. We review recent progress made in lattice calculations of spatial static quark anti-quark correlators as well as quarkonium correlators in Euclidean time.

QCD factorization for hadronic quarkonium production at high $p_T$
SciPost Physics Proceedings, 2022 Heavy quarkonium production at high transverse momentum ($p_T$) in hadronic collisions is explored in the QCD factorization approach. We find that the leading power in the $1/p_T$ expansion is responsible for high $p_T$ regime, while the next-to-leading

Heavy quarkonia in a potential model: binding energy, decay width, and survival probability
European Physical Journal C: Particles and Fields, 2018 Recently a lot of progress has been made in deriving the heavy quark potential within a QCD medium. In this article we have considered heavy quarkonium in a hot quark gluon plasma phase.

Quarkonium transport in weakly and strongly coupled plasmas [PDF]
EPJ Web of ConferencesWe report on progress in the nonperturbative understanding of quarkonium dynamics inside a thermal plasma. The time evolution of small-size quarkonium is governed by two-point correlation functions of chromoelectric fields dressed with an adjoint Wilson ...

The Quarkonium Analysis of the QGP [PDF]
EPJ Web of Conferences, 2014 Quarkonium production has been considered as a tool to study the medium formed in high energy nuclear collisions, assuming that the formation of a hot and dense environment modifies the production pattern observed in elementary collisions. The basic features measured there are the relative fractions of hidden to open heavy flavor and the relative ...
