The elliptic ($v_2$), triangular ($v_3$), and quadratic ($v_4$) flow harmonic backgrounds are subtracted using the Zero Yield At Minimum (ZYAM) method. The results are compared to minimum-bias d+Au collisions. It is found that a finite near-side ($|\\Delta\\phi|<\\pi/2$) long-range pseudorapidity correlation (ridge) is present in the in-plane direction ($\\phi_{s}\\sim 0$). The away-side ($|\\Delta\\phi|>\\pi/2$) correlation shows a modification from d+Au data, varying with $\\phi_{s}$. The modification may be a consequence of pathlength-dependent jet-quenching and may lead to a better understanding of high-density QCD.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.97120.v1/t1","@type":"Dataset","description":"raw correlation, Au+Au 200 GeV, 20-60%, 3<p_{T}^{(t)}<4 GeV/c, 1<p_{T}^{(a)}<2 GeV/c, |#eta|<1,
