Description
Short-lived hadronic resonances are used to study different aspects of particle production
and collision dynamics in pp, p—A and relativistic heavy-ion collisions. The yields of
resonances are sensitive to the competing processes of hadron rescattering and regeneration,
thus making these particles unique probes of the properties of the late hadronic phase.
Measurements of resonances with different masses and quantum numbers also provide insight
into strangeness production and processes that determine the shapes of particle momentum
spectra at intermediate transverse momenta, as well as the species dependence of hadron
suppression at high momentum.
Thanks to a campaign of precise measurements, the ALICE experiment now has a comprehensive
set of results with unprecedented precision for $\rho(770)^{0}$, K$^{*}(892)$, $f_{0}(980)$,
$\phi(1020)$, $\Sigma(1385)^{\pm}$, $\Lambda(1520)$, and $\Xi(1530)^{0}$ production in pp,
p—Pb, Xe-Xe and Pb-Pb collisions in the energy range $\sqrt{s_{\rm NN}}$ = 2.76-13 TeV,
including the latest measurements from LHC Run 2. The obtained results are used to study
the system-size and collision-energy evolution of transverse momentum spectra, particle
ratios and nuclear modification factors and to search for the onset of collectivity in
small collision systems. These results are compared to lower energy measurements and
model calculations where available.
