We calculate the production of large transverse momentum dileptons and photons by using direct and resolved photoproduction processes in relativistic heavy ion collisions. Considering the central collisions of heavy n...

The cold component of large transverse momentum dilepton production via semi-coherent two- photon interaction is calculated. The cold contribution is essential to the dilepton spectra in the soft region for different ...

In the paper we discuss the role of the axial U(1)A symmetry in the chiral phase transition using the U(Nf)R × U(Nf)L linear sigma model with two massless quark flavors. It is expected that above a certain temp...
