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 ...

ALICE at the LHC provides unique capabilities to study charmonium production at low transverse momenta (pT). At central rapidity, (|y| < 0.8), ALICE can reconstruct J/ψ via their decay into two electrons down to zero pT. ...

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 ...

We report measurements of two jet shapes, the ratio of 2-Subjettiness to 1-Subjettiness (τ2/τ1) and the opening angle between the two axes of the 2-Subjettiness jet shape, which is obtained by reclustering the jet with the ...

The characterisation of the jet substructure can give insight into the microscopic nature of the modification inducedon high-momentum partons by the Quark-Gluon Plasma that is formed in ultra-relativistic heavy-ion collisions. ...

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 ...

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 ...

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 multiplicity distributions over a wide pseudorapidity range ( −3.4<η<5.0 ) for pp collisions at s√=0.9,7 , and 8 TeV at the LHC. Results are based on information from the Silicon Pixel ...

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 ...
