Study of isolated-photon and jet momentum imbalance in pp and PbPb collisions

Nuclear Physics B, 2018
In this paper, we study the production of isolated-photon plus a jet in pp and PbPb collisions, which can be used as an important probe to the jet transport property in quark gluon plasma created in heavy ion collisions.

The Quark Gluon Pion Plasma

, 2002
While it is commonly believed that there is a {\it direct} transition from the hadronic to a quark gluon phase at high temperature, it would be prejudicial to rule out a sequence of dynamically generated intermediate scales.

Jet quenching of the heavy quarks in the quark-gluon plasma and the nonadditive statistics

Physics Letters B
Using the Plastino-Plastino (PP) equation, we calculate transport coefficients of the heavy-quarks traversing inside the quark-gluon plasma, and generalize their relationship with differential energy loss. The PP equation indicates anomalous diffusion of

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

Induced photon emission from quark jets in ultrarelativistic heavy-ion collisions

, 2004
We study the induced photon bremsstrahlung from a fast quark produced in AA-collisions due to multiple scattering in quark-gluon plasma. For RHIC and LHC conditions the induced photon spectrum is sharply peaked at photon energy close to the initial quark

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 ...

Matching pre-equilibrium dynamics and viscous hydrodynamics

, 2010
We demonstrate how to match pre-equilibrium dynamics of a 0+1 dimensional quark gluon plasma to 2nd-order viscous hydrodynamical evolution. The matching allows us to specify the initial values of the energy density and shear tensor at the initial time of

Dynamic scaling and quenching for heavy quark in the linear expanding medium

European Physical Journal C: Particles and Fields
We study the energy loss of the heavy quark and the heavy quark jet propagating through linear expanding quark–gluon plasma (QGP). We show that the concept of scaling is valid for heavy quarks, with the quenching parameter of the equivalent static media ...

Physics of the Quark-Gluon Plasma

, 1992
Central nuclear collisions at energies far above 1 GeV/nucleon may provide for conditions, where the transition from highly excited hadronic matter into quark matter or quark-gluon plasma can be probed.

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
