Measurement with the ATLAS detector of multi-particle azimuthal correlations in p+Pb collisions at sNN=5.02 TeV

In order to study further the long-range correlations (“ridge”) observed recently in p+Pb collisions at sNN=5.02 TeV, the second-order azimuthal anisotropy parameter of charged particles, v2, has been measured with the cumulant method using the ATLAS detector at the LHC. In a data sample correspondi...

Description
Summary:In order to study further the long-range correlations (“ridge”) observed recently in p+Pb collisions at sNN=5.02 TeV, the second-order azimuthal anisotropy parameter of charged particles, v2, has been measured with the cumulant method using the ATLAS detector at the LHC. In a data sample corresponding to an integrated luminosity of approximately 1 μb−1, the parameter v2 has been obtained using two- and four-particle cumulants over the pseudorapidity range |η|
