Double Helicity Asymmetry in ${\pi }^0$ Production at Midrapidity in Polarized $p+p$ Collisions at $\sqrt{s}=510$ GeV

Inseok Yoon

PHENIX measurements are presented for the cross-section and double-helicity asymmetry ($A_{LL}$) of inclusive ${\pi }^0$ production ($A_{LL}^{{\pi }^0}$) at midrapidity from $p+p$ collis…
