Observation of Associated Near-Side and Away-Side Long-Range Correlations in √s NN =5.02 TeV Proton-Lead Collisions with the ATLAS Detector

Two-particle correlations in relative azimuthal angle (Δρ) and pseudorapidity (Δη) are measured in √s NN =5.02 TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1 μb - 1 of data as a function of transverse momentum (p T ) and the transverse e...
