Hadronic Resonances in Heavy-Ion Collisions at ALICE
A. G. Knospe (for the ALICE Collaboration)
TL;DR
This paper reports measurements of the phi(1020) and K*(892)0 resonance properties in Pb-Pb collisions at 2.76 TeV, exploring potential signs of chiral symmetry restoration through modifications in resonance spectra.
Contribution
It provides the first measurements of resonance masses and widths in heavy-ion collisions at LHC energies, comparing them across different collision systems.
Findings
Resonance spectra, masses, and widths were measured in Pb-Pb collisions.
Comparisons with other collision systems were performed.
Results may indicate modifications related to chiral symmetry restoration.
Abstract
Modifications to the masses and widths of hadronic resonances in heavy-ion collisions could be a sign of chiral symmetry restoration. Uncorrected spectra, masses, and widths of the phi(1020) and K*(892)0 resonances have been measured in Pb-Pb collisions at 2.76 TeV using the ALICE detector. These measurements are presented and compared to resonances in other collision systems.
