Physics Division Seminars bring us speakers on a variety of physics related subjects. Usually these are held in the Building 6008 large Conference Room, at 3:00 pm on the chosen day, but times and locations may vary. For more information, contact our seminar chairman,

One of the most interesting observations at the Relativistic Heavy Ion Collider (RHIC) has been the suppression of particles with high transverse momenum (pT) in central Au+Au collisions compared to peripheral collisons and to expectations from proton+proton results.
It has been suggested that particle production at high transverse momenta, which is largely due to the fragmentation of jets, might be suppressed as a result of parton energy loss in a dense medium like the quark-gluon plasma. However, it is not possible to distinguish in Au+Au collisions between these so called initial state effects and effects of cold nuclear matter at sqrt sNN = 200 A · GeV. This is possible in Deuteron-Gold Collsions which have been studied during the last RHIC beamtime.
