Abstract
Here we present initial studies of two-dimensional angular correlations of Λ, Λ, and K0Short triggers with unidentified charged hadrons in Au+Au collisions at \(\sqrt{s_{NN}}\) =200 GeV measured by STAR. Distributions of pseudo-rapidity difference, Δη, and azimuthal separation, Δφ, are constructed containing structures observed in unidentified hadron correlations, including a jet peak at small Δη-Δφ accompanied by a flow-like ridge extended over Δη. These features are studied as a function of centrality via integrated yields and fitting to projections onto Δη and Δφ axes. Yields are found to be consistent with unidentified correlation analyses, and no clear distinction is observed between the three species.
