- Descripción
- Measurements of two-particle correlation functions and the first five azimuthal harmonics, v1 to v5, are presented, using 28 nb−1 of p+Pb collisions at a nucleon-nucleon center-of-mass energy of sNN=5.02 TeV measured with the ATLAS detector at the LHC. Significant long-range ?ridgelike? correlations are observed for pairs with small relative azimuthal angle (|Δϕ|<π/3) and back-to-back pairs (|Δϕ|>2π/3) over the transverse momentum range 0.4

Significant long-range ?ridgelike? correlations are observed for pairs with small relative azimuthal angle (|Δϕ|<π/3) and back-to-back pairs (|Δϕ|>2π/3) over the transverse momentum range 0.4<pT<12 GeV and in different intervals of event activity.

The v1 is also measured as a function of pT and is observed to change sign around pT≈1.5?2.0 GeV and then increase to about 0.1 for pT>4 GeV.
