Medium effect on photon production in ultrarelativistic nuclear collisions
Chung-sik Song, George Fai
The effect of in-medium vector and axial-vector meson masses on photon production is studied. We assume that the effective mass of a vector meson in hot nuclear matter decreases ac…
Excess of pions with chiral symmetry restoration
Chungsik Song, Volker Koch
We study the effect of the chiral phase transition on pion production in hot hadronic matter. The phase of restored chiral symmetry is characterized by the appearance of the scalar…
Chemical relaxation time of pions in hot hadronic matter
Chungsik Song, Volker Koch
We calculate characteristic time scales for chemical equilibration of pions in hot hadronic matter using an effective chiral Lagrangian. We find that inelastic processes involving…
Pion electromagnetic form factor at finite temperature
Chungsik Song, Volker Koch
Temperature effects on the electromagnetic couplings of pions in hot hadronic matter are studied with an effective chiral Lagrangian. We show that the Ward-Takahashi identity is sa…
Dilepton Production at SPS-energy Heavy Ion Collisions
V. Koch, C. Song
The production of dileptons is studied within a hadronic transport model. We investigate the sensitivity of the dilepton spectra to the initial configuration of the hadronic phase…
Role of the meson in dilepton production from hot hadronic matter
Chungsik Song, Che Ming Ko, Charles Gale
Dilepton production from hot hadronic matter is studied in an effective chiral Lagrangian with pions, -mesons, and mesons, We find that the production rates from reactions…
