Jets and produced particles in<i>pp</i>collisions from SPS to RHIC energies for nuclear applications

Abstract

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