Abstract:
Measurement of the flow coefficients $v_2$ and $v_3$ as a function of transverse momentum $\pT$ in central $^{3}$He+Au, $d$+Au, and $p$+Au collisions at $\sqrtsNN$ = 200 GeV are presented. The measurement, obtained via two-particle azimuthal angular correlations with four different subtraction methods to mitigate non-flow correlations, gives consistent results within the uncertainties. The magnitudes and trends of the $v_2(\pT)$ and $v_3(\pT)$ values, as well as the ratios between the three small systems are consistent with an important influence from both sub-nucleonic eccentricity fluctuations and size-driven viscous attenuation. Comparison to hydrodynamic model calculations suggest that further theoretical and experimental investigations are required to pin down the influence from initial-state momentum anisotropy and pre-equilibrium reaction dynamics.
Fig.1:Two-particle per-trigger yield distributions for $^3$He+Au, $d$+Au, $p$+Au, and \pp collisions at $\sqrtsNN$ = 200 GeV as indicated; the trigger and associated particles are selected in the range $0.2 < \pT < 2.0$~GeV/c and $|\eta| <$ 0.9. An illustration of the template fitting procedure, which employs the MB \pp correlator to estimate the non-flow contributions and extract the $v_2$ and $v_3$ flow coefficients, is also shown.
Fig.2:Comparison of the flow coefficients $v_2$ (left column) and $v_3$ (right column), in $0\%-10\%$ $^{3}$He+Au, $0\%-10\%$ $d$+Au, and UC $p$+Au collisions without and with four different non-flow subtraction methods ( see text). Only statistical uncertainties are shown.

Fig.3:Comparison of the $v_2$ and $v_3$ from data and hydrodynamic model calculations, in $0\%-10\%$ $^{3}$He+Au, $0\%-10\%$ $d$+Au, and UC $p$+Au collisions. The calculated results are obtained from three hydrodynamic models: {\sc sonic}~\cite{Nagle:2013lja,sonic}, {\sc supersonic}~\cite{sonic,Nagle:2013lja}, and the IP-Glasma+MUSIC ~\cite{Schenke_2020,schenke2020running}
