The suppression of neutral pion production in high-energy heavy-ion
collisions was one piece of evidence of parton energy loss in the hot
medium produced at RHIC and thus a convincing signature for the
Quark-Gluon Plasma (QGP). The p(d)+A system had previously been
considered as a baseline to study the cold nuclear matter effects that
are also present in A+A collisions but are difficult to disentangle from
the effects of the QGP. Recently, measurements from p(d)+A have
indicated that there may be effects from a strongly interacting medium
even in these systems. In further study of these interesting systems,
RHIC collided $^3$He+Au in 2014 and p+Au in 2015. A comparison of the
p$_T$ and centrality dependent yields, as well as R$_{AA}$, will
contribute to the systematic study of these systems. In this poster, we
report the $\pi^0$ yields and R$_{AA}$ in $^3$He+Au, d+Au, and p+Au
collisions at $\sqrt{s_{NN}}$ = 200 GeV at PHENIX.
