Disentangling centrality bias and final-state effects in the production of high-$p_T$ ${\pi }^0$ using direct $\gamma$ in $d$$+$Au collisions at $\sqrt{s_{{}_{NN}}}=200$ GeV

PHENIX presents a simultaneous measurement of the production of direct $\gamma$ and ${\pi }^0$ in $d$$+$Au collisions at $\sqrt{s_{{}_{NN}}}=200$ GeV over a $p_T$ range of 7.5 to 18 GeV/$c$ fo…
