We present a measurement of pi-\pi+, K-/K+ and pbar/p from p+p collisions at sqrt(s) = 20 0GeV over the rapidity range 0<y<3.4. For pT < 2.0 GeV/c we see no significant transverse momentum dependence of the ratios. All three ratios are…

Per-trigger yields of $\pi^0$-hadron correlations were measured in semicentral Pb-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV in ALICE at the LHC. The reconstructed $\pi^0 \rightarrow \gamma \gamma$, with a transverse momentum of $11 <…

High multiplicity proton-proton and proton-lead collisions at LHC energies exhibit similar signatures to those observed in Pb-Pb collisions (i.e. the strangeness enhancement, the ridge behaviours etc.), that were commonly attributed to the…
