摘要：

Higher-order perturbative QCD corrections play an important role in the reproduction of data at high transverse momenta in the energy range 20 GeV less than or equal to roots less than or equal to 200 GeV. Recent calculations of photon and pion production in pp collisions yield detailed information on the next-to-leading-order (NLO) contributions. However, the application of these results in proton-nucleus and nucleus-nucleus collisions is not straightforward. The study of nuclear effects requires a simplified understanding of the output of these computations. Here we summarize our analysis of recent calculations, aimed at handling the NLO results by introducing process and energy-dependent K factors.
