Hadronic matter - matter susceptible to the strong interaction force - is described by quantum-chromo-dynamics (QCD). The basic constituents of QCD are quarks which interact through the exchange of gluons. It is believed that shortly after the creation of the universe in the Big Bang all matter was in a state called the Quark Gluon Plasma (QGP). Due to the rapid expansion of the Universe, this plasma went through a phase transition to form hadrons - most importantly nucleons - which constitute the building blocks of (nuclear) matter as we know it today. The investigation of QGP properties will yield important novel insights into the development of the early universe and the behavior of QCD under extreme conditions.
It is hoped to recreate this highly excited state of primordial matter
under controlled laboratory conditions using relativistic heavy ion collisions,
e.g. at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National
Laboratory. In my talk I will review the current status of QGP research
and discuss the latest results from experiments at the Relativistic Heavy-Ion
Collider and their implications.
*Dr. Bass obtained his Ph.D. degree in 1997 from Johann Wolfgang Goethe
Universitaet,
Frankfurt, Germany. He is currently an assistant professor of
physics at Duke University with a joint appointment at the RIKEN/BNL Theory
Center of the Brookhaven National Laboratory in New York. His research
involves the application of transport theory, statistical mechanics, heavy-ion
collision phenomenology, as well as the fundamental laws of strong interactions.
Dr. Bass is a renowned expert on transport theory.
