Suppression of back-to-back Hadron Pairs at forward rapidity in d+Au collisions at √sNN=200GeV

Abstract

Back-to-back hadron pair yields in d+Au and p+p collisions at √s NN=200GeV were measured with the PHENIX detector at the Relativistic Heavy Ion Collider. Rapidity separated hadron pairs were detected with the trigger hadron at pseudorapidity η<0.35 and the associated hadron at forward rapidity (deuteron direction, 3.0
