We review the various aspects of anisotropic quark-gluon plasma (AQGP) that have recently been discussed by a number of authors. In particular, we focus on the electromagnetic probes of AQGP, inter quark potential, quarkonium states in AQGP, and the nuclear modifications factor of various bottomonium states using this potential. In this context, we will also discuss the radiative energy loss of partons and nuclear modification factor of light hadrons in the context of AQGP. The features of the wake potential and charge density due to the passage of jet in AQGP will also be demonstrated.

Abstract We perform an analysis of jet quenching in heavy and light ion collisions for scenarios without and with quark-gluon plasma formation in pp collisions. We find that the results for these scenarios are very similar, and both of them are in reasonable agreement with data for heavy ion collisions. However, their results become differ significantly for light nuclei. Using the parameters fitted to heavy ion data on the nuclear modification factor RAA, we make predictions for 0.2 and 7 TeV O+O collisions that can be verified by future experiments at RHIC and the LHC.

▪ Abstract  We review the propagation of energetic partons in hot or cold QCD matter, as known from recent work. We summarize advances in the understanding of both collisional and radiative energy loss. Our emphasis is on radiative energy loss, which has very interesting properties that may help to detect the quark-gluon plasma produced in heavy-ion collisions. We describe two different theoretical approaches, which lead to the same radiated gluon energy spectrum. The case of a longitudinally expanding QCD plasma is investigated. The energy lost by a jet with given opening angle is calculated with the aim of making predictions for the suppression (quenching) of hard jet production. Phenomenological implications for the difference between hot and cold matter are discussed. Numerical estimates of the loss suggest that it may be significantly greater in hot matter than in cold. This makes the magnitude of the radiative energy loss a remarkable signal for quark-gluon plasma formation.

It has been argued recently that the so-called nuclear modification factor (RAA) is an observable useful for identifying the quark–gluon plasma. We discuss the effect of Fermi motion in nuclei on RAA at CERN SPS and BNL RHIC energies. Contrary to the simple intuition, rather large effects are found for CERN SPS. The Fermi motion in nuclei contributes significantly to the Cronin effect. The effect found is qualitatively similar to the one observed experimentally at CERN energies and similar to the one obtained in the models of multiple scattering of initial partons. We predict different size of the effect for different types of hadrons, especially at low energies.

Abstract The baryon-to-meson ratio Λ c + / D 0 and the nuclear modification factor RAA in the charm sector are important observables to gain an understanding of how charm quarks hadronise and lose energy in the Quark-Gluon Plasma produced in heavy-ion collisions. In this contribution, recent measurements performed with the ALICE detector in pp, p–Pb and Pb–Pb collisions at 5.02 TeV are presented and compared with previous measurements in pp collisions at 7 TeV, measurements by the LHCb Collaboration and theoretical model predictions.
