systems' nuclear interferometry" The subject of the measurments are
two-particle nucleon and light nuclear fragments correlations. The goal
is the analysis of time-space evolution of the particle emission
process in heavy ion reactions, and of related effects, such as
deuteron formation mechanisms, the role of coulomb effects, emission
sequence of different particle types, etc.
subject of our analysis are nuclei collisions at the highest achievable
energies of 200GeV per nucleon in the center of mass system. We examine
nuclear matter properties in extremal density and temperature. We
search for signs of transition into the so called Quark Gluon Plasma
phase (QGP - a hypothetical state of matter that is believed to have
existed during the early stage of the Universe evolution).
- A Large Ion Collider Experiment, is one of the biggest physical
experiments in the world which is being prepared in the European
Particle Physics Centre - CERN. The subject of the experiment regards
the creation and analysis of the properties of a new state of nuclear
matter, in which quarks and gluons won't be tied together in complex
systems (hadrons), but will be in the form of the so called "Quark
Gluon Plasma" (QGP).
the experimental data from the E286 experiment realized in GANIL, we
analyze nuclear reactions mechanisms in the area of mid-energies at the
order of tens of MEV per nucleon. The theoretical description bases on
computer modelling of nuclear reactions using the Monte-Carlo methods.
Correlations of hadrons emitted with low relative velocities (HBT+FSI)
analysis of particles emitted with low relative velocities allows to
estimate space-time properties of the properties in which the particles
have been emitted. This area of interest is an essential element of
nuclear reactions mechanisms analysis at high energies.
PStrange particle productions in heavy ion collisions
carry on computer simulations, whose goal is the analysis of the
possibility of strange particle study in the upcoming ALICE experiment
through registration of their decay products. In particular we consider
the attempt to identify strange quark systems called "strangelets".
complex process of relativistic heavy ion collisions can't be described
using analitical methods and is modeled with the use of Monte-Carlo
methods. Our group carries out event generation using existing models
such as HIJING, RQMD, UrQMD, NEXUS, and furthermore we participate in
research aiming at the creation of a hybrid model combining the quick
phase, the hydrodynamic expansions process, hadronization and secondary
effects including resonance production.
Experimental techniques: data-bases and data acquisition systems
P.Gutowski, M.Słodkowski, M.Szuba, J.Radzimiński
the frame of the ALICE experiment our group works on creating,
installing in local centres and in CERN, and on exploatation of the
data-base system containing complex information regarding the
construction of all ALICE detector elements ("Detector Construction
Data Base, DCDB"). Members of our group also participate in the
construction and programming of a data acquisition system ("Data
AcQuisition, DAQ") for the Silicon Strip Detectors (SSD).
