Description
The study of resonance production is important in proton-proton, proton-nucleus, and heavy-ion collisions.
Since the lifetimes of short-lived resonances are comparable with the lifetime of the late hadronic phase
produced in heavy-ion collisions, resonance measurable yields are affected by regeneration and rescattering.
These competing effects are investigated by measuring the yield ratios of resonances to that of
the corresponding longer-lived hadron as a function of multiplicity. From these measurements, it is possible
to obtain information on the time interval between the chemical and kinetic freeze-out.
The measurements in pp and p-Pb collisions constitute a reference for nuclear collisions
and provide information for tuning event generators inspired by Quantum Chromodynamics.
In this talk, recent results on short-lived hadronic resonances obtained with ALICE at LHC energies are presented.
These results include system-size and collision-energy evolution of transverse momentum spectra,
yields and the ratios of resonance yields to those of longer-lived particles, and nuclear modification factors.
The results will be compared with model predictions and measurements at lower energies.
