(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
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, ...

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 ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
The second and the third order anisotropic flow, V2 and V3, are determined by the corresponding initial spatial anisotropy coefficients, ε2 and ε3, in the initial density distribution. On the contrary, the higher order ...

We present the charged-particle pseudorapidity density in pp, p–Pb, and Pb–Pb collisions at √sNN = 5.02 TeV over a broad pseudorapidity range. The distributions are determined using the same experimental apparatus and ...

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 ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
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 ...

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 ...

Elliptic (v2) and higher harmonic (v3, v4) flow coefficients of π±, K±, p(p), and the φ-meson, measured in Pb-Pb collisions at the highest-ever center-of-mass energy of √sNN = 5.02 TeV, are presented. The results were ...
