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 ...

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 ...
