Abstract

Measurements of two-particle correlation functions and the first five azimuthal harmonics, v(1) to v(5), are presented, using 28 nb(-1) of p + Pb collisions at a nucleon-nucleon center-of-mass energy of root s({NN}) = 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 ({\textbar}Delta phi{\textbar} {\textless} pi/3) and back-to-back pairs ({\textbar}Delta phi{\textbar} {\textgreater} 2 pi/3) over the transverse momentum range 0.4 {\textless} p(T) {\textless}
