Hadronic resonance production in pp and Pb-Pb collisions at LHC with the ALICE experiment
Abstract
Resonances, with their lifetimes comparable to that of the fireball, can be used to estimate the time span and hadronic interaction cross section in the phase between chemical and kinetic freeze-out. In pp collisions, measurements of resonances provide an important baseline for heavy-ion data and allow for the tuning of QCD-inspired particle production models. The ALICE collaboration measured K*(892) and phi(1020) production, both in pp collisions at TeV and in Pb-Pb collisions at TeV. The inelastic yield of Σ(1385)± in pp collision at TeV was also measured. Transverse momentum spectra, ratios to stable particles and a comparison between central and peripheral production are shown.
