Description
Two-particle correlations in p Pb collisions at a nucleon-nucleon
center-of-mass energy of 5.02 TeV are studied as a function of the
pseudorapidity separation (Δ η ) of the particle pair at small
relative azimuthal angle (|Δ ϕ |<π /3 ). The
correlations are decomposed into a jet component that dominates the
short-range correlations (|Δ η |<1 ), and a component that
persists at large Δ η and may originate from collective
behavior of the produced system. The events are classified in terms of
the multiplicity of the produced particles. Finite azimuthal
anisotropies are observed in high-multiplicity events. The second and
third Fourier components of the particle-pair azimuthal correlations,
V2 and V3, are extracted after subtraction of the
jet component. The single-particle anisotropy parameters v2
and v3 are normalized by their laboratory frame midrapidity
value and are studied as a function of ηc.m.. The
normalized v2 distribution is found to be asymmetric about
ηc.m.=0 , with smaller values observed at forward
pseudorapidity, corresponding to the direction of the proton beam, while
no significant pseudorapidity dependence is observed for the normalized
v3 distribution within the statistical uncertainties.
