Effect of Event Selection on Jetlike Correlation Measurement in d + Au Collisions at √s[subscript NN] = 200 GeV

[摘要] Dihadron correlations are analyzed in √s[subscript NN] = 200 GeV d+Au collisions classified by forward charged particle multiplicity and zero-degree neutral energy in the Au-beam direction. It is found that the jetlike correlated yield increases with the event multiplicity. After taking into account this dependence, the non-jet contribution on the away side is minimal, leaving little room for a back-to-back ridge in these collisions.
