Nuclear Physics & RIKEN Theory Seminar

"Characterizing the QCD X-Matter from the Little Bang"

Presented by Jinfeng Liao, Lawrence Berkeley Natl Laboratory

Friday, January 22, 2010, 2:00 pm — Small Seminar Room, Bldg. 510

ABSTRACT: In this talk, I will report some progresses in characterizing the hot QCD matter (call it an "X-matter") created in the heavy ion collisions, which is the only experimentally accessible example of a strongly coupled plasma in a non-Abelian gauge theory. I will mainly discuss: (1) how "perfect" this matter is as a fluid e.g. when compared with all other fluids, and in particular what is the proper measure for such a comparison. Furthermore I will also briefly discuss: (2) whether the matter's microscopic degrees of freedom are more chromo-electric or -magnetic, and how that characterization is related to QCD confinement; (3) whether the fermions in this matter are more free or more correlated or even bound; (4) what "opaque" pattern this matter has, when imaged by a highly energetic penetrating jet.
