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. ...

The second and the third order anisotropic flow, V2and V3, are mostly determined by the corresponding initial spatial anisotropy coefficients, ε2and ε3, in the initial density distribution. In addition to their dependence on ...

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 ...

Particle production at LHC energies involves the interplay of hard (perturbative) and soft (non-perturbative) QCD processes. Global observables, such as the charged-particle multiplicity, are related to the initial geometry ...

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 ...

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 ...

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 ...

Direct photon production in heavy-ion collisions provides a valuable set of observables to study the hot QCD medium. The direct photons are produced at different stages of the collision and escape the medium unaffected. ...

In ultrarelativistic heavy-ion collisions, the event-by-event variation of the elliptic flow v2 reflects fluctuations in the shape of the initial state of the system. This allows to select events with the same centrality ...
