The energy dependence of the $v_1(y)$ slope, $dv_{1}/dy|_{y=0}$, for deuterons, where $y$ is the rapidity, is extracted for semi-central collisions (10-40\\% centrality) and compared to that of protons. While the $v_1(y)$ slopes of protons are generally negative for $\\sqrt{s_{NN}} >$ 10 GeV, those for deuterons are consistent with zero, a strong enhancement of the $v_1(y)$ slope of deuterons is seen at the lowest collision energy (the largest baryon density) at $\\sqrt{s_{NN}} =$ 7.7 GeV. In addition, we report the transverse momentum dependence of $v_1$ for protons and deuterons. The experimental results are compared with transport and coalescence models.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95544.v1/t1","@type":"Dataset","description":"The 1st-order event plane ($\\Psi_{1}$) resolution as a function of centrality of Au+Au collisions at $\\sqrt{s_{NN}}$ = 7.7, 11.5, 14.5,...","name":"Fig3"},{"@id":"https://doi.org/10.17182/hepdata.95544.v1/t2","@type":"Dataset","description":"Rapidity dependene of $v_1$ for protons(open squares) in 10-40 \\%Au+Au collisions at $\\sqrt{s_{NN}}$ = 7.7, 11.5, 14.5, 19.6, 27, and...","name":"Fig4_proton"},{"@id":"https://doi.org/10.17182/hepdata.95544.v1/t3","@type":"Dataset","description":"Rapidity dependene of $v_1$ for deuterons(solid circles) in 10-40 \\%Au+Au collisions at $\\sqrt{s_{NN}}$ = 7.7, 11.5, 14.5, 19.6, 27, and...","name":"Fig4_deuteron"},{"@id":"https://doi.org/10.17182/hepdata.95544.v1/t4","@type":"Dataset","description":"Directed flow slope at mid-rapidity, $dv_{1}/dy|_{y=0}$, as a function of beam energy in 10-40\\% Au+Au collisions.
