    Paper

    Recently, multiparticle-correlation measurements of relativistic \(p/d/^3\)He\(+\)Au, $p$$+\(Pb, and even \)p$$+$$p\( collisions have shown surprising collective signatures. Here we present beam-energy-scan measurements of 2-, 4-, and 6-particle angular correlations in \)d$$+\(Au collisions at \)\sqrt{s_{_{NN}}}\(=200, 62.4, 39, and 19.6 GeV. We also present measurements of 2- and 4-particle angular correlations in \)p$$+\(Au collisions at \)\sqrt{s_{_{NN}}}\(=200 GeV. We find the 4-particle cumulant to be real-valued for \)d$$+\(Au collisions at all four energies. We also find that the 4-particle cumulant in \)p$$+\(Au has the opposite sign as that in \)d$$+\(Au, indicating that the correlations are geometrical and therefore collective in origin. Further we find that the 6-particle cumulant agrees with the 4-particle cumulant in \)d$$+$Au collisions at 200 GeV, which indicates that nonflow effects are subdominant and provides strong evidence of collectivity.
