Effect of event selection on jetlike correlation measurement in $d$+Au collisions at $sqrt{s_{rm{NN}}}=200$ GeV


الملخص بالإنكليزية

Dihadron correlations are analyzed in $sqrt{s_{_{rm NN}}} = 200$ 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.
