Physics Colloquium, September 28, 2004SIZE MATTERS: SPACETIME GEOMETRY in RELATIVISTIC HEAVY ION COLLISIONSMichael A. LisaDepartment of Physics, The Ohio State UniversityRelativistic heavy ion (RHI) physics is a rapidly expanding area of study. Having its roots in nuclear physics, RHI concepts and experimental techniques merge also with high energy or particle physics. I will briefly discuss the field and its goals, concentrating on the crucial feature distinguishing RHI physics as a field-- non-trivial spacetime dynamics. The overall goal of the field-- to study the transition between confined and deconfined colored matter-- depends strongly on geometry both to create the deconfined state and to extract its properties. I will discuss some of the recent progress in understanding the system created in RHI collisions at the highest attainable energies and the role geometry continues to play in these studies. 3.30 p.m., Smith Laboratory, Room 1005Refreshments served in Smith 1094 at 3:00 p.m. |
