Next-to-leading-logarithm calculation of jet photoproduction

Abstract

A Monte Carlo program containing both leading-logarithm and next-to-leading-logarithm contributions has been developed and used to study the photoproduction of large-transverse-momentum hadronic jets. Predictions are presented and discussed for a variety of observables including singlejet invariant cross sections, dijet cross sections, and angular distributions. For some observables the inclusion of the next-to-leading-logarithm terms dramatically lessens the dependency on the choice of the renormalization and factorization scales entering the calculation, thereby increasing the precision of the calculation. The flexibility of the Monte Carlo technique allows predictions for additional observables to be generated easily.
