CIJET: A program for computation of jet cross sections induced by quark contact interactions at hadron colliders

Abstract

We describe CIJET1.0, a Fortran program aimed at calculating single-inclusive jet or dijet production cross sections induced by quark contact interactions from new physics at hadron colliders, up to next-to-leading order in QCD. It covers various contact interactions with different chiral and color structures. The code is designed in a way that could be used for fast calculations with arbitrary parton distribution functions based on interpolations of the QCD coupling constant and parton distribution functions.
