Measurement of emission-angle anisotropy via long-range angular correlations with high-pT hadrons in d plus Au and p plus p collisions at root s(NN)=200 GeV

Original language description

We present measurements of two-particle angular correlations between high-transverse-momentum (2 &lt; pT &lt; 11 GeV/c) pi(0) observed at midrapidity (|eta| &lt; 0.35) and particles produced either at forward (3.1 &lt; eta &lt; 3.9) or backward (-3.7 &lt; eta &lt; -3.1) rapidity in d + Au and p + p collisions at root s(NN) = 200 GeV. The azimuthal angle correlations for particle pairs with this large rapidity gap in the Au-going direction exhibit a characteristic structure that persists up to pT approximate to 6 GeV/c and which strongly depends on collision centrality, which is a similar characteristic to the hydrodynamical particle flow in A + A collisions. The structure is absent in the d-going direction as well as in p + p collisions, in the transverse-momentum range studied. The results indicate that the structure is shifted in the Au-going direction toward more central collisions, similar to the charged-particle pseudorapidity distributions.
