Abstract.

We review the phenomenology of \(\pi^0\) production at large transverse momentum in proton-induced collisions. Uncertainties in the next-to-leading-order predictions of Quantum Chromodynamics are discussed. The comparison with data reveals that the disagreement between theory and experiment lies essentially in an overall normalization factor. The situation for \(\pi^0\) production is contrasted with that of prompt-photon production in hadronic collisions.
