G.Stefanek and the ALICE
ALICE (A Large Ion Collider Experiment) is a
dedicated heavy ion experiment at the LHC. The goal of the
experiment is to study strongly interacting matter at extreme energy
densities (QCD thermodynamics). Statistical QCD predicts that, at
sufficiently high densities, there will be a transition from
hadronic matter to a plasma of deconfined quarks and gluons - a
transition which in the early universe took place about 100
micro-seconds after the Big Bang. The study of nuclear collisions at
high energies utilizes methods and concepts from both nuclear and
high energy physics constituting a new and interdisciplinary
approach in investigating matter and its interactions.
The ALICE collaboration proposes to build a dedicated, general-purpose
detector that will utilize the full potential of the LHC programme
including both nucleus-nucleus and proton-proton collisions. Its
design is based on the experiencies gained with the existing
programs at CERN and BNL and it will address a majority of known
sensitive observables like hadrons, di-leptons and photons. The
ALICE detector will be the only heavy ion experiment at LHC and its
design has therefore to be conservative and robust to be able to
observe most of the signals that look promosing today for the QGP
Members of the group participate in the development and the construction of
PHOton Spectrometer. We take part in beam tests of the detector prototype
and data analysis. We are also involved in the preparation of the online monitoring software.
