Description
Particle ratios provide insight into the hadrochemistry of the event and the mechanisms for particle production. In Pb-Pb collisions the relative multi-strange baryon yields exhibit an enhancement with respect to pp collisions, whereas the short-lived K$^{*0}$ resonance is suppressed in the most central events due to re-scattering. Measurements in p-Pb allow us to investigate the development of these effects as a function of the system size.
We report comprehensive results on light-flavour hadron production measured with the ALICE detector in p--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV, covering a wide range of particle species which includes long-lived hadrons, resonances and multi-strange baryons.
The measurements include the transverse momentum spectra and the ratios of spectra among different species, and extend over a very large transverse momentum region, from ~100 MeV/$c$ to ~20 GeV/$c$, depending on the particle species.
