New results related to QGP-like effects in small systems with ALICE

Abstract

Results on the production of ${\pi }^{\pm }$, ${\text{K}}^{\pm }$, $\text{p}(\bar{\text{p}})$, $\Lambda (\bar{\Lambda })$, ${\Xi }^{-}\left({\bar{\Xi }}^{+}\right)$ and ${\Omega }^{-}\left({\bar{\Omega }}^{+}\right)$ at midrapidity ($|y|<0.5$) as a function of multiplicity in $\sqrt{s}=7\text{TeV}$ pp collisions are reported. Transverse momentum distributions and integrated yields are compared to expectations from statistical hadronization models along with results from different colliding systems and center-of-mass energies. The evolution of spectral shapes with multiplicity show similar patterns to those seen in p-Pb and Pb-Pb collisions. The $p_{\text{T}}$-integrated baryon yields relative to pions exhibit a significant strangeness-related enhancement in both pp and p-Pb collisions.
