An overview of resonance measurements at the ALICE experiment

Resonances play a unique role in the study of ultra-relativistic heavy-ion collisions. Resonance yields, which may be modified by rescattering and regeneration after hadronization, can be used to study the properties of the hadronic phase of the collision. The transversemomentum spectra of the proto...
