Electromagnetic Probes of Dense Matter in Relativistic Heavy-ion Collisions
Dilepton and photon production in heavy-ion collisions at SPS energies is studied in the relativistic transport model that incorporates self-consistently the change of hadron masses in dense matter. It is found that the dilepton spectra in protonnucleus reactions can be well described by the conventional mechanisms of Dalitz decay, primary vector meson decay, decay of charmed mesons, and the in...

Dilepton and photon production in heavy-ion collisions at SPS energies are studied in the relativistic transport model that incorporates self-consistently the change of hadron masses in dense matter. It is found that the dilepton spectra in proton-nucleus reactions can be well described by the conventional mechanism of Dalitz decay and direct vector meson decay. However, to provide a quantitati...
متن کاملStrange Hadron Resonances: Freeze-Out Probes in Heavy-Ion Collisions
Hyperon resonances are becoming an extremely useful tool allowing the study of the properties of hadronic fireballs made in heavy ion collisions. Their yield, compared to stable particles with the same quark composition, depends on hadronization conditions. The resonance’s short lifetime makes them ideal probes of the fireball chemical freeze-out mechanisms. An analysis of resonance abundance i...
متن کاملHard Probes in High-energy Heavy-ion Collisions
Hard QCD processes in ultrarelativistic heavy-ion collisions become increasingly relevant and they can be used as probes of the dense matter formed during the violent scatterings. We will discuss how one can use these hard probes to study the properties of the dense matter and the associated phenomenologies. In particular, we study the effect of jet quenching due to medium-induced energy loss o...
متن کاملCoherent Electromagnetic Processes in Ultra-Peripheral Heavy-Ion Collisions
We report measurements for coherent ρ production, AuAu→AuAuρ, and coherent ρ and ee pair production accompanied by mutual nuclear Coulomb excitation, AuAu→AuAuρ and AuAu → Au∗Au∗ + ee, in ultra-peripheral relativistic gold-gold collisions (UPC). We discuss transverse momentum, mass, and rapidity distributions. The two photon-process of ee pair production is an important probe of strong field QE...
