Representations of Fermionic Correlators at Finite Temperatures
The symmetry group of the staggered Fermion transfer matrix in a spatial
direction is constructed at finite temperature. Hadron-like operators carrying
irreducible representations of this group are written down from the breaking of
the zero temperature group. Analysis of the correlators in a free fermion
theory suggests new measurements which can test current interpretations.Comment: Plain LaTeX, no figure
A short introduction to heavy-ion physics
Heavy-ion collisions provide the only laboratory tests of relativistic
quantum field theory at finite temperature. Understanding these is a necessary
step in understanding the origins of our universe. These lectures introduce the
subject to experimental particle physicists, in the hope that they will be
useful to others as well. The phase diagram of QCD is briefly touched upon.
Kinematic variables which arise in the collisions of heavy-ions beyond those in
the collisions of protons or electrons are introduced. Finally, a few of the
signals studied in heavy-ion collisions, and the kind of physics questions
which they open up are discussed.Comment: Lectures delivered at the Asia-Europe-Pacific School of High-Energy

Finding the critical end point of QCD: lattice and experiment
The current status of the search for the critical end point on the lattice
and in experiments is discussed. A naive extrapolation is given of lattice
results on the location of the critical end point to the continuum limit with
the correct pion mass. An interpretation of current results on fluctuations is
provided. A new method of analysis of experimental data is discussed, which
provides a check on the removal of backgrounds, comparisons with QCD, and
signals an approach to the critical end point.Comment: 5 pages, 1 figure. Talk given in CPOD 200
