Prof. Dr. Michael Strickland, Kent State University, is a renowned expert on finite-temperature quantum field theory and hydrodynamics in heavy-ion collisions. He is currently collaborating with Prof. Brambilla and her group on the problem of the nonequilibrium evolution of quarkonium in the quark-gluon plasma.
Abstract: Relativistic heavy-ion collision experiments at Brookhaven National Laboratory in the US and at CERN have made it possible to experimentally turn back the clock to microseconds after the Big Bang; a time when matter, as we know it, did not exist. At these early times, the temperature of the universe was on the order of 10^12 Kelvin (~ 100’s of MeV) and protons and neutrons, which constitute atomic nuclei, had not yet been formed. Instead, the universe was a super-hot plasma of quarks and gluons called the quark-gluon plasma (QGP). In this talk, I will review the theoretical tools necessary to understand the quark-gluon plasma in the early universe and now being formed in terrestrial relativistic heavy-ion collisions. I will discuss a few key heavy-ion experimental observables, such as collective flow, jet energy loss, and heavy-quarkonium suppression, which all point to the creation of a QGP with an initial temperature of 600-700 MeV at the LHC.
