"Studying the Quark Gluon Plasma at the LHC"

Abstract: In ultra-relativistic heavy ion collisions a fireball of hot and dense matter is created. When the energy density inside the fireball is very high, liberation of partons is expected to occur and a new phase of matter, the Quark Gluon Plasma (QGP) is formed. Short-lived hadronic resonances are sensitive to the medium properties of a heavy-ion collision, in particular to the temperature, density and expansion velocity. Hadronic resonances are measured with the ALICE detector at the LHC. The results of the heavy ion Pb-Pb collisions are discussed with new a model, which can describe the full evolution of the collision. New data from p-p and p-Pb collisions will be discussed with respect to the question if a QGP can be formed in such small collision systems.
