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.
