Hadronic resonance production in Pb-Pb collisions at the ALICE experiment

Measurements of the yields of hadronic resonances (relative to non-resonances) in high-energy heavy-ion collisions allow the chemical freeze-out temperature and the time between chemical and thermal freeze-out of the collision system to be studied, while modifications to resonance masses and widths...

description Measurements of the yields of hadronic resonances (relative to non-resonances) in high-energy heavy-ion collisions allow the chemical freeze-out temperature and the time between chemical and thermal freeze-out of the collision system to be studied, while modifications to resonance masses and widths could be a signature of chiral symmetry restoration. The spectra (for pT < 5 GeV/c), total integrated yields, ratios to non-resonances (phi/pi and phi/K), mass, and width of the phi(1020) meson and the uncorrected yields, mass, and width of the K*(892)0 and anti-K*(892)0 mesons have been measured using the ALICE detector for Pb-Pb collisions at 2.76 TeV. These measurements will be compared to results from other collision systems and energies. Angular correlations between leading trigger hadrons and phi(1020) mesons have been measured in Pb-Pb and pp collisions; the mass and width of the phi(1020) meson as a function of the correlation angle will be presented.
