Dihadron momentum imbalance and correlations in d+Au collisions, Z. Kang; Brookhaven National Laboratory, Upton, New York, USA − In recent years, there has been renewed interest in nuclear effects that affect hadronic observables in proton-nucleus (p+A) and deuteron-nucleus (d+A) collisions.  In this work, by taking into account both initial- and final-state multiple parton scattering inside the nucleus, we calculate in perturbative QCD the transverse momentum imbalance (nuclear-induced broadening) of dijet and dihadron production in high energy p+A (d+A)  collisions. The nuclear-induced broadening can be used to calculate the width of the away-side peak in dihadron correlation measurements.  Combining this new result with the suppression of the cross section in d+Au collisions, which arises from cold nuclear matter energy loss and coherent power corrections, we are able to describe the dihadron correlations measured recently by both PHENIX and STAR collaborations at RHIC, including mid-mid, mid-forward, and forward-forward rapidity hadron pairs.
