Description
Asymmetric collisions of large nuclei at high energy offer a unique
window into many aspects of excited medium formation and evolution.
Unlike symmetric collisions, an asymmetric system can have non-zero
odd-order moments in its average transverse distribution of
participants, and the pattern of participants from the two nuclei
can have different shapes on average. In 2012, PHENIX measured
particle production in Cu$+$Au collisions at
$\sqrt{s_{_{NN}}}=200$~GeV, and we report measurements of the
azimuthal anisotropies $v_1$, $v_2$, and $v_3$ (directed, elliptic,
and triangular flow) for inclusive and identified charged hadrons
produced at midrapidity. Implications for a variety of unique
initial-state geometry effects will be discussed.
