Description
Hadronic resonances are effective tools for studying the hadronic phase in ultrarelativistic heavy-ion collisions. In fact, their lifetime is comparable to that of the hadronic phase, and resonances are sensitive to effects such as rescattering and regeneration processes, which might affect the resonance yields and shape of the transverse momentum spectra. These processes can be studied considering the yield ratio of resonance to the corresponding long-lived particle as a function of the charged-particle multiplicity. Measurements of hadronic resonances have been performed with the ALICE detector at the LHC in pp, p--Pb, and Pb--Pb collisions at different energies.
In this contribution, we report on new ALICE results on the production of resonances at LHC energies in pp, p--Pb, and Pb--Pb collisions. The transverse momentum ($p_{\mathrm{T}}$) spectra, $p_{\mathrm{T}}$-integrated yields, and ratios of $p_{\mathrm{T}}$-integrated resonance yields to those of long-lived particles will be discussed as a function of multiplicity in all collision systems. Additionally, the experimental results obtained will be compared with the theoretical predictions.
