RELATIVISTIC HEAVY ION PHYSICS
The research interests of the
Relativistic Heavy Ion Physics group are focused on heavy ion collisions at ultrarelativistic energies, which is an
exciting new field on the borderline between nuclear and high
energy physics. Over the last two decades our group has primarily
studied the following three topics:
- Nuclear Matter at Extreme Temperatures and Densities: We are
investigating the properties of nuclear matter at high densities and
temperatures with special emphasis on detecting the Quark-Gluon Plasma (QGP),
which is a postulated new phase of nuclear matter where quarks and
gluons are deconfined over a large volume.
- Modification of Vector Meson Properties in Hot and Dense Nuclear
Matter: Among the many proposed signatures for the QGP, we are
convinced that the proposed modifications of the properties of vector
mesons in hot and dense nuclear matter provides the best tool for
observing the QGP and for measuring the properties of the QGP. We are
specifically studying the production of the J/psi and the Upsilon
resonances using the PHENIX muon detector.
- Nuclear Stopping Power and Attained Energy Densities: The
most important prerequisite for the creation of the QGP in
ultra-relativistic heavy ion reactions is a large nuclear stopping power
so that sufficiently high energy densities will be achieved in the
central fireball. We have studied this topic through calorimetric
measurements at WA98 and through slow proton emission in the target
fragmentation region at E910.
Brief Vita
I was born on August 24, 1950 in Denmark and grew up in the suburbs of
Copenhagen. I attended the University of Copenhagen
and majored in Math and Physics. In 1977 I received a Masters Degree
from The Niels
Bohr Institute (Thesis: "Fusion of 16O + 16O") and in 1981 got the PhD from the same place (Thesis: "Quasielastic Transfer Reactions
induced by 56Fe on 58Ni, 64Ni and 122Sn"). From 1981 to 1984 I was a post-doc at The Niels
Bohr Institute, and spent a year from 1982-83 at
Oak Ridge National Laboratory. In
December 1984 I began my appointment at The
University of Tennessee as an assistant professor in nuclear physics.
I have a Volunteer ever since, apart from 18 months as a visitor at
CERN, Geneva in 1986-87.
