The High Energy Group at Jan Kochanowski University studies collisions of atomic nuclei accelerated to relativistic energies. The aim of such studies is to explore and understand the properties of matter at extreme temperatures (~10¹² degrees) and densities (>10 times nuclear matter density). In particular, we are interested in characterizing the transition from normal hadronic matter to the Quark-Gluon Plasma, a state of matter consisting of deconfined quarks and gluons. We study collisions of heavy nuclei at the highes possible energies. Our interests concentrate on several topics:

• Particle Production


• Fluctuations (intermittency)


• Onset of Deconfinement


• Isospin Symmetry Violation


• Charm Production

This research involves collaborative experiments at CERN (WA93/WA98, NA49, ALICE). Members of the group are involved with detector and software development (WA98, ALICE), data taking and analysis (WA98, NA49) and theoretical description of Quark Gluon Plasma.
