Abstract

This chapter of thesis work has been summarized in [4, 5].The deuteron–gold (d+Au) collisions at RHIC were initially proposed as a control experiment to disentangle cold nuclear effect and hot QGP final state effect for the strong suppression of high-p T particles in central heavy-ion collisions [69]. The naive expectation for the small d+Au system is that only the cold nuclear matter effect needs to be considered, where little or no collective flow as a signature of QGP can develop. The observation of the long-range \(\Delta \eta\) dihadron correlation at small \(\Delta \phi\) (called the ridge) in p + p and p+Pb collisions at the Large Hadron Collider (LHC) [1013] was, therefore, unexpected. As discussed in Sect. 1.5, the ridge was first discovered in heavy-ion collisions and was primarily attributed to triangular anisotropic flow.
