Effects of Higher-Order Threshold Corrections in High-ET Jet Production
Nikolaos Kidonakis, J. F. Owens
Abstract
Results for higher-order threshold enhancements in high-ET jet production in hadron-hadron collisions are presented. Expressions are given for the next-to-next-to-leading order (NNLO) threshold corrections to the single-jet inclusive cross section at next-to-leading logarithmic (NLL) accuracy. The corrections are found to be small for the specific choice of ET/2 for the factorization and renormalization scales, and the corrected cross section shows a substantial reduction of the scale dependence. A comparison to experimental results from the Tevatron is presented.
