Elliptic Flow Measurements with the PHENIX Detector
Two particle azimuthal correlation functions are presented for charged
hadrons produced in Au+Au collisions at RHIC ( GeV). The
measurements allow for the determination of elliptic flow without
event-by-event estimation of the reaction plane. The measured correlation
functions indicate elliptic flow values () which show significant
sensitivity to both the collision centrality and the transverse momenta of
emitted hadrons.Comment: Contribution to Quark Matter 2001, Long Island, New York, January

Influence of finite volume and magnetic field effects on the QCD phase diagram
The Polyakov linear sigma model (PLSM) is used to investigate the respective
influence of a finite volume and a magnetic field on the quark-hadron phase
boundary in the plane of baryon chemical potential () vs. temperature
() of the QCD phase diagram. The calculated results indicate sizable shifts
of the quark-hadron phase boundary to lower values of
for increasing magnetic field strength, and an opposite shift to higher values
of for decreasing system volume. Such shifts could
have important implications for extraction of the thermodynamic properties of
the QCD phase diagram from heavy ion data
