We show that in asymmetric heavy-ion collisions, especially off-central Cu+Au collisions, a sizable strength of electric field directed from Au nucleus to Cu nucleus is generated in the overlapping region, because of the difference in the…
This talk will discuss how heavy ion experiments, when moving from SPS (10 + 10 GeV) to RHIC (100+100 GeV) and to LHC (2750+2750 GeV), will enter a new domain of QCD in which the production of even large pT gluons is so abundant that it is…
Quantum Chromodynamics (QCD), the theory of strong interactions, in principle describes the interaction of quark and gluon fields. However, due to the self-coupling of the gluons, quarks and gluons are confined into hadrons and cannot exist…
