Bremsstrahlung from Electrons and Positrons in Peripheral Relativistic Heavy Ion Collisions
We study the spectrum of the bremsstrahlung photons coming from the electrons and positrons, which are produced in the strong electromagnetic fields present in peripheral relativistic heavy ion collisions. We compare different approaches, making use of the exact pair production cross section in heavy ion collisions as well as the double equivalent photon approximation. 25.75.-q,13.40.-f Typeset...
متن کاملRecent Results from Heavy Ion Collisions
The purpose of the current heavy ion programs at CERN (Switzerland) and Brookhaven National Laboratory (USA) is to probe strongly interacting matter under extreme conditions, i.e. at high densities and temperatures. The central subject of these studies is the transition from the quark-gluon plasma to hadronic matter. In the early phases of ultra-relativistic heavy ion collisions, when a hot and...
متن کاملIdentifying multiquark hadrons from heavy ion collisions.
Identifying hadronic molecular states and/or hadrons with multiquark components either with or without exotic quantum numbers is a long-standing challenge in hadronic physics. We suggest that studying the production of these hadrons in relativistic heavy ion collisions offers a promising resolution to this problem as yields of exotic hadrons are expected to be strongly affected by their structu...
متن کاملFrom QCD to heavy ion collisions
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 simultaneously perturbative but such that the phase space density of gluons is saturated. The saturation scale psat is estimated, quantitative numbers for th...
