The medium-induced p⊥-broadening and induced gluon radiation spectrum of a high energy quark or gluon traversing a large nucleus is studied. Multiple scattering of the high energy parton in the nucleus is treated in the Glauber approximation. We show that −dE/dz, the radiative energy loss of the parton per unit length, grows as L, the length of the nuclear… (More)

Jefferson Lab Experiment PR12-06-117, Quark Propagation and Hadron Formation, was approved in 2006 by PAC 30. Since that time there have been many new developments concerning the related physics topics, which we summarize in this document. These developments only serve to increase the relevance and urgency of the original proposal; this 12 GeV experiment… (More)

This report reviews the study of open heavyflavour and quarkonium production in high-energy hadronic collisions, as tools to investigate fundamental aspects of Quantum Chromodynamics, from the proton and nucleus structure at high energy to deconfinement and the properties of the Quark–Gluon Plasma. Emphasis is given to the lessons learnt from LHC Run 1… (More)

We study the non-abelian, gauge invariant, screening potential between two charges in a quark-gluon plasma. Using Braaten and Pisarski resummed perturbation theory in temporal axial gauge, we find a repulsive power screened potential which behaves as ∼ 1/r at large distance. This questions either the physical meaning of the Debye mass or the known pragmatic… (More)

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. The average energy loss ∆E depends on the particle energy E and mass M , the plasma temperature T , the QED (QCD) coupling constant α (αs), and the distance L the… (More)

We examine again the problem of the damping rate of a moving heavy fermion in a hot plasma within the resummed perturbative theory of Pisarski and Braaten. The ansatz for its evaluation which relates it to the imaginary part of the fermion propagator pole in the framework of a self-consistent approach is critically analyzed. As already pointed out by… (More)

Within an explicit scalar QED model we compare, at fixed x ≪ 1, the leading-twist K⊥-dependent ‘quark’ distribution fq(x,K⊥) probed in deep inelastic scattering and Drell-Yan production, and show that the model is consistent with the universality of fq(x,K⊥). The extension of the model from the aligned-jet to the ’symmetric’ kinematical regime reveals… (More)
