Description
Azimuthal momentum anisotropies have now been observed in
small collision systems at RHIC and the LHC. At RHIC, using the unique
ability to select different colliding species, the PHENIX experiment has
taken data in p+Al, p+Au, d+Au, and 3He+Au at 200 GeV center-of-mass
energy. This geometry engineering allows for a unique test of
explanations of azimuthal anisotropy
in terms of final state effects versus initial state momentum domain
effects. In this talk, we report on elliptic anisotropies in all systems
for unidentified hadrons as well as particle identified hadrons. We
also report on triangular anisotropies comparing d+Au and 3He+Au
results. Detailed model comparisons with all observables are discussed.
