We review the present status in the theoretical and phenomenological understanding of charmonium and bottomonium production in heavy-ion collisions. Starting from an introductory historical perspective, recapitulating the basic notion of “anomalous quarkonium suppression” in heavy-ion collisions, we develop ingredients and concepts aimed at a comprehensive approach to utilize heavy quarkonia as...

The initial conditions in high energy nucleus-nucleus collisions are determined by the small momentum fraction part of the nuclear wavefunction. This is the regime of gluon saturation and the most direct way to experimentally study it would be deep inelastic scattering at a high energy electron ion collider (EIC). This talk discusses some of the connections between physics at the EIC and the in...

In ρ photoproduction in ultra-peripheral heavy ion collisions, either ion can be the photon emitter or the target. The two possibilities are indistinguishable, and they should be able to interfere, reducing rho production at low transverse momentum, pT < h̄/〈b〉, where 〈b〉 is the median impact parameter. The two ρ production points are separated by 〈b〉 ≈ 18−46 fm, while the ρ decay before travell...

The early stages of a relativistic heavy-ion collision are examined in the framework of an effective classical SU(3) Yang-Mills theory in the transverse plane. We compute the initial energy and number distributions, per unit rapidity, at midrapidity, of gluons produced in high-energy heavy-ion collisions. We discuss the phenomenological implications of our results in light of the recent Relativ...

ALICE will study the physics of the strongly interacting matter produced in nucleus-nucleus collisions at the LHC where the formation of the Quark Gluon Plasma is expected. The experimental setup, the capabilities of the detector, and a few selected heavy-ion topics will be presented and discussed. Quantum Chromodynamics (QCD) predicts a transition from a stable state of matter formed by hadron...

DETERMINATION OF JET TRANSPORT PARAMETERS AND THEIRTEMPERATURE DEPENDENCE IN HEAVY-ION COLLISIONS

We attempt to deduce simple options of ‘jet quenching’ phenomena in heavy-ion collisions at

2014 The available experimental and theoretical results on ion induced X-rays are briefly surveyed. From experimental data it may be concluded that the mechanism for inner shell excitation by heavy ion-atom collisions is different from that for proton-atom collisions. The latter are described successfully in Plane Wave Born Approximation (PWBA) and in classical Binary Encounter Approximation (B...
