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

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