Following an argument by Kirzhnits we derive an exact expression for the collisional energy loss of a fast charged particle in a relativistic plasma using quantum field-theoretical language. We compare this result to perturbative calculations of the collisional energy loss of an energetic electron or muon in an electron-positron plasma and of an energetic parton in the quark-gluon plasma.

Quenching of hadron spectra due to the collisional energy loss of partons in the quark-gluon plasma
We estimate the energy loss distribution and investigate the quenching of hadron spectra in ultrarelativistic heavy-ion collisions due to the collisional energy loss of energetic partons from hard
Energy losses in a hot plasma revisited
We present a mini-review of the problem of evaluating the energy loss of a ultrarelativistic charged particle crossing a thermally equilibrated high temperature e+e- or quark-gluon plasma.
Energy loss of charm quarks in the quark-gluon plasma: Collisional vs radiative losses
In considering the collisional energy loss rates of heavy quarks from hard light parton interactions, we computed the total energy loss of a charm quark for a static medium. For the energy range
The QGP Discovered at RHIC
Three empirical lines of evidence, (P QCD , p QCD, dA), from RHIC have converged and point to the discovery of a strongly coupled Quark Gluon Plasma. The evidence includes (1) bulk collective
Open heavy flavor production from single muons in PHENIX at RHIC
The PHENIX experiment has studied open heavy flavor production in $\sqrt{s_{NN}}$ =200 GeV p+p and d+Au collisions using the semi-leptonic decay into single muons. The results from these measurements
The dielectric function of nuclear matter excited by ρNN tensor coupling has been studied in the framework of finite temperature field theory. The induced current mechanism has been introduced to
Energy losses of positive and negative charged particles in electron gas
A heavy charged particle propagation through electron gas has been studied using combination of non-relativistic quantum mechanics and the Green’s functions method. The energy loss of a charged

The energy loss for a heavy lepton propagating through a high-temperature QED plasma is calculated to leading order in the QED coupling constant using a resummation of perturbation theory in the small-momentum-transfer region.
Quark-Gluon Plasma
An elementary introduction to the physics of quark-gluon plasma is given. We start with a sketchy presentation of the Quantum Chromodynamics which is the fundamental theory of strong interactions.
Equilibrium and non-equilibrium hard thermal loop resummation in the real time formalism
Abstract. We investigate the use of the hard thermal loop (HTL) resummation technique in non-equilibrium field theory. We use the Keldysh representation of the real time formalism (RTF). We derive

Under conditions relevant to ultrarelativistic heavy-ion collisions, charm quarks and bottom quarks lie on opposite sides of the crossover energy and therefore experience significantly different energy losses.
