Abstract

Results on the production of π±\pi^{\pm}, K±\textrm{K}^{\pm}, p(pˉ)\textrm{p}(\bar{\textrm{p}}), Λ(Λˉ)\Lambda(\bar{\Lambda}), Ξ(Ξˉ+)\Xi^{-} \left(\bar{\Xi}^{+}\right) and Ω(Ωˉ+)\Omega^{-} \left(\bar{\Omega}^{+}\right) at midrapidity (y<0.5{|y|<0.5}) as a function of multiplicity in s = 7 TeV\sqrt{s}~=~7~\textrm{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 pTp_{\textrm{T}}-integrated baryon yields relative to pions exhibit a significant strangeness-related enhancement in both pp and p-Pb collisions.
