We present a calculation for single-inclusive large-${p}_{T}$ pion production in longitudinally polarized $\mathrm{pp}$ collisions in next-to-leading order QCD. We choose an approach where fully analytical expressions for the underlying partonic hard-scattering cross sections are obtained. We simultaneously rederive the corresponding corrections to unpolarized scattering and confirm the results existing in …
