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. Program Summary Program title : CIJET 1.0 Catalogue identifier : AEPQ_v1_0 Program summary URL : http://cpc.cs.qub.ac.uk/summaries/AEPQ_v1_0.html Program obtainable from : CPC Program Library, Queen’s University, Belfast, N. Ireland Licensing provisions : Standard CPC licence, http://cpc.cs.qub.ac.uk/licence/licence.html No. of lines in distributed program, including test data, etc. : 13087 No. of bytes in distributed program, including test data, etc. : 331957 Distribution format : tar.gz Programming language : Fortran; with some included libraries coded in C. Computer : All. Operating system : Any UNIX-like system. RAM : 300 MB Classification : 11.1. External routines : LHAPDF ( https://lhapdf.hepforge.org/ ) Nature of problem : Calculation of single-inclusive jet and dijet cross sections induced by quark contact interactions up to next-to-leading order in QCD at hadron colliders. Solution method : Using the VEGAS Monte Carlo sampling and subtracted matrix element to generate weight grids and store them in a table file that allows for later interpolations on arbitrary parton distribution functions. Running time : Depends on the details of the calculation and the required numerical accuracy.
