Description
The presence of a strongly interacting medium produced in relativistic
heavy-ion (AA) collisions modifies the final transverse momentum (p$_{\mathrm{T}}$) spectra of hadrons with respect to proton-proton (pp) collisions. While the production at high-p$_{\mathrm{T}}$ is suppressed by in-medium energy loss of high-p$_{\mathrm{T}}$ partons, at lower p$_{\mathrm{T}}$ other mechanisms dominate strangeness production. In order to explore this issue, a system size scan of the production rates of strange
hadrons is warranted.
The ALICE Collaboration reports on the nuclear modification factors R$_{\mathrm{AA}}$
and R$_{\mathrm{pA}}$ of several light-flavour hadrons, including (multi)strange particles.
In addition, we also explore the crucial issue of how strangeness production scales with system size by presenting recent results on the multiplicity dependence of light-flavour production in pp collisions. The results are compared to measurements from lower energies and to predictions from QCD-inspired event generators.
