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 could be a signature of chiral symmetry restoration. The spectra (for p_T < 5 GeV/c), total integrated yields, ratios to non-resonances (ϕ/π and ϕ/K), mass, and width of the ϕ(1020) meson and the uncorrected yields, mass, and width of the K*(892)⁰ and mesons have been measured using the ALICE detector for Pb-Pb collisions at TeV. These measurements will be compared to results from other collision systems and energies. Angular correlations between leading trigger hadrons and ϕ(1020) mesons have been measured in Pb-Pb and pp collisions; the mass and width of the ϕ(1020) meson as a function of the correlation angle will be presented.
