Elliptic flow of ${\pi }^0$ mesons in Cu$+$Au collisions at $\sqrt{s_{{}_{NN}}}=200$ GeV and U$+$U at $\sqrt{s_{{}_{NN}}}=193$ GeV

The second-order azimuthal anisotropy coefficients ($v_2$) of neutral $\pi$ mesons (${\pi }^0$) have been measured as a function of the transverse momentum ($p_T$) and centrality of Cu$+$…
