Dihadron azimuthal correlations at large pseudo-rapidity difference in multiplicity-selected d+Au collisions by STAR

Abstract

The long-range pseudo-rapidity correlations observed in pp and p+Pb collisions at the LHC have stimulated extensive interest. The tantalizing observation of similar effect by PHENIX calls for careful examination of the RHIC d+Au data. In this talk, we present dihadron correlations in multiplicity-selected d+Au collisions by STAR, in both $\Delta \varphi$ and $\Delta \eta$ and from both TPC and FTPC.
