Abstract
We review the phenomenology of
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
production is
contrasted with that of prompt-photon production in hadronic collisions.
