Ultra-peripheral Pb-Pb collisions, in which the two nuclei pass close to each other, but at an impact parameter greater than the sum of their radii, provide information about the initial state of nuclei. In particular, ...

Highlights of recent results from the ALICE collaboration are presented. The collision systems investigated are Pb–Pb, p–Pb, and pp, and results from studies of bulk particle production, azimuthal correlations, open and ...

Strangeness production is a key tool to understand the properties of the medium formed in heavy-ion collisions: an enhanced production of strange particles was early proposed as one of the signatures of the Quark-Gluon ...

The study of identified particle production as a function of transverse momentum (pT) and event multiplicity in protonproton (pp) collisions at different center-of-mass energies (√s) is a key tool for understanding ...

The availability at the LHC of the largest collision energy in pp collisions allows a significant advance in the measurement of J/ψ production as function of event multiplicity. The interesting relative increase observed ...

First experimental results are presented on event-by-event net-proton fluctuation measurements in Pb- Pb collisions at √sNN = 2.76 TeV, recorded by the ALICE detector at the CERN LHC. The ALICE detector is well suited for ...

We report measurement of the semi-inclusive distribution of charged-particle jets recoiling from a high transverse momentum (pT) hadron trigger, for p–Pb collisions at √sNN = 5.02 TeV, in p–Pb events classified by event ...

Two- and multi-particle azimuthal correlations have proven to be an excellent tool to probe the properties of thestrongly interacting matter created in heavy-ion collisions. Recently, the results obtained for multi-particle ...

W and Z bosons are massive weakly-interacting particles, insensitive to the strong interaction. They provide therefore a medium-blind probe of the initial state of the heavy-ion collisions. The final results for the W and ...

Two-particle correlations in relative azimuthal angle (Δφ) and pseudorapidity (Δη) have been used to study heavy-ion collision dynamics, including medium-induced jet modification. Further investigations also showed the ...
