Effect of event selection on jetlike correlation measurement in d + Au collisions at sNN=200 GeV

Dihadron correlations are analyzed in sNN=200 GeVd+Aud+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.
