Charged-pion cross sections and double-helicity asymmetries in polarized p+p collisions at s=200 GeV
A. Adare, C. Aidala, N. N. Ajitanand, Y. Akiba et autres
We present midrapidity charged-pion invariant cross sections, the ratio of the ${\ensuremath{\pi}}^{\ensuremath{-}}$ to ${\ensuremath{\pi}}^{+}$ cross sections and the charge-separated double-spin asymmetries in polarized $p+p$ collisions at $\sqrt{s}=200\text{ }\mathrm{GeV}$. While the cross section measurements are consistent within the errors of next-to-leading-order (NLO) perturbative …
