In this Letter, comprehensive results on pi(+/-), K-+/-, K-S(0), p((p) over bar) and A((A) over bar) production at mid-rapidity (0 < y(CMS) < 0.5) in p-Pb collisions at root s(NN) = 5.02 TeV, measured by the ALICE detector at the LHC, are reported. The transverse momentum distributions exhibit a hardening as a function of event multiplicity, which is stronger for heavier particles. This behavior is similar to what has been observed in pp and Pb-Pb collisions at the LHC. The measured pr distributions are compared to d-Au, Au-Au and Pb-Pb results at lower energy and with predictions based on QCD-inspired and hydrodynamic models. (C) 2013 The Authors.

• The Muon Puzzle in cosmic-ray induced air showers and its connection to the Large Hadron Collider (2021, methodology): “The potential key to the Muon Puzzle was discovered by the ALICE collaboration, which found a universal strangeness and baryon enhancement in p-p, p-Pb and Pb-Pb (Abelev et al. 2014b; Adam et al. 2016c, 2017b; Vasileiou 2020).”
