Hadronic resonance probing the medium created in heavy ion collisions at LHC energies.

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. Resonance yields and momentum distributions are used to gain inside of the hadronic phase and its time duration. I will discuss mainly the centrality and multiplicity depended K(892) and phi(1020) measurements from Pb-Pb, p-Pb and pp collisions from the ALICE experiment.
