Theory Summary

Abstract

I also include some remarks on a possible interpretation of the recent observation that the sound velocity squared may be of the order or exceed 1/3 at a few times nuclear matter density, as determined by neutron star observations.

Effect of magnetic field on dilepton production in a hot plasma

“…According to the present understanding, the two nuclei colliding at ultra relativistic energies appear as two sheets of Color Glass Condensate [16]. Very shortly after collision a strongly interacting Quark Gluon system, called Glasma, is formed, which is out of thermal equilibrium [17][18][19][20]. After thermalization it gives rise to the Quark Gluon plasma (QGP) phase.…”
