Selected topics from experimental studies at RHIC
H. Hamagaki
Major goal of the studies with ultra-high energy heavy ion
collisions is to realize a new phase of hadronic matter, called quark
gluon plasma, and to study properties of such exotic matter. Many new
results are being reported from the experimental studies at
Relativistic Heavy Ion Collider (RHIC) at Brookhaven National
Laboratory, USA, which started operation in 2000.
In this short lecture, I aim to cover the followings; (1)basic
knowledge of the strong interactions, where QCD is introduced and
the problem of confinement will be discussed, (2) properties of
hadronic interactions, where a string model and Bjorken's picture on the
space-time evolution are described, (3) QCD matter and heavy ion
collisions, where QCD phase transition is introduced and heavy ion
collisions are introduced as a unique tool to attack this interesting
subject, and (4) topical results, where some of the results from the
RHIC experiments are resented.
