Recently the PHENIX Collaboration has made available two-particle correlation Fourier coefficients for multiple detector combinations in minimum bias $p+p$ and 0--5% central $p+\mathrm{Au}$, $d+\mathrm{Au}$, $^{3}\mathrm{He}+\mathrm{Au}$ collisions at $\sqrt{{s}_{{}_{NN}}}$ = 200 GeV [Phys. Rev. C 105, 024901 (2022)]. Using these three sets of correlations, azimuthal anisotropy ${v}_{2}$ ${v}_{3}$ are extracted midrapidity charged hadrons as a function transverse momentum. In this paper, we use to explore various nonflow hypotheses well compare results with theoretical model calculations. The methods fail basic closure tests ampt pythia/angantyr, particularly when including correlations particles low multiplicity light-projectile going direction. data, adjusted modestly lower $p+\mathrm{Au}$ more significantly higher $d+\mathrm{Au}$. However, resulting values ratio ${v}_{3}/{v}_{2}$ RHIC compared $p+\mathrm{Pb}$ LHC is additional evidence significant overcorrection. Incorporating checks, conclusion that flow dominated by initial geometry coupled final-state interactions (e.g., hydrodynamic expansion quark-gluon plasma) remains true, explanations based solely on initial-state glasma ruled out. detailed balance between intrinsic fluctuation-driven exact role weakly versus strongly prehydrodynamic evolution an open question triangular flow, requiring further experimental investigation.
