Charmonium production and elliptic flow in relativistic heavy-ion collisions
EPJ Web of Conferences, 2011 Using the two-component model for charmonium production, which includes contributions from both initial hard nucleon-nucleon scattering and from regeneration in the quark-gluon plasma, we have studied the nuclear modification factor RAA and elliptic flow

Jet conversions in a quark-gluon plasma [PDF]
, 2007 Quark and gluon jets traversing through a quark-gluon plasma not only lose their energies but also can undergo flavor conversions. The conversion rates via the elastic $q(\bar q)g\to gq(\bar q)$ and the inelastic $q\bar q\leftrightarrow gg$ scatterings ...

Heavy quarkonium dissociation by thermal gluons at next-to-leading order in the Quark–Gluon Plasma
Physics Letters B, 2018 Using the chromo-electric dipole coupling Hamiltonian from QCD multipole expansion, we derive the dissociation cross sections of heavy quarkonia by thermal gluons at next-to-leading order (NLO, also known as inelastic parton scattering dissociation) in ...

The jet quenching in high energy nuclear collisions and quark-gluon plasma
, 2003 e investigate the energy loss of quark and gluon jets in quark-gluon plasma produced in central Au+Au collisions at RHIC energy. We use the physical characteristic of initial and mixed phases, which were found in effective quasiparticle model for SPS and

Application of AdS/CFT in Quark-Gluon Plasma
Advances in High Energy Physics, 2013 We review some important applications of AdS/CFT correspondence to gain insight into properties of the quark-gluon plasma. We study some important quantities such as drag force, screening length, and jet-quenching parameter of an external probe quark and

Heavy quarkonia in a bulk viscous medium
Journal of High Energy Physics, 2020 We study the properties of heavy quarkonia in a quark gluon plasma in the presence of bulk viscous effects. Within the hard thermal loop approximation at one-loop, the dielectric permittivity of a quark gluon plasma is computed, where the bulk viscous ...

Toward a solution to the RAA and v2 puzzle for heavy quarks
Physics Letters B, 2015 The heavy quarks constitute a unique probe of the quark–gluon plasma properties. A puzzling relation between the nuclear modification factor RAA(pT) and the elliptic flow v2(pT) has been observed both at RHIC and LHC energies.

T -matrix approach to quark-gluon plasma [PDF]
, 2017 A selfconsistent thermodynamic $T$-matrix approach is deployed to study the microscopic properties of the quark-gluon plasma (QGP), encompassing both light- and heavy-parton degrees of freedom in a unified framework.
