G.Stefanek and the WA98
The WA98 experiment (an extension of the previous
WA93 and WA80 experiments) utilized the newly developed Pb-beams at
CERN SPS in November and December of 1994. The main goal of the
experiment is to study the emission of thermal photons with high
precision. These are supposed to be one of the best probes of a
transition from the hadronic state of matter to a phase of
"quasi"-free quarks and gluons (QGP) because of their weak
interaction with the surrounding hot and dense hadronic
matter. The WA98 experiment also measure flow of various
particles, two-,three- particle correlations and study DCC domains.
One of members ( G.Stefanek ) actively participate
in preparation of the Plastic Ball detector to the WA98 experiment.
Polish group was responsible for the development and construction
of the whole electronic system of the Plastic Ball spectrometer.
A modified version of the software was prepared and used during
data taking in 1994-1996. Polish group is actively involved in the analysis
of the data from WA98 experiment. The primary physical fenomena
we are interested in are "FLOW" and "Bose-Einstein correlations".
