(PDF description)



TOPIXS can be used to compute the total top-antitop production cross section at the Tevatron and the LHC. The cross section can be computed either at fixed order in perturbation theory up to approximate next-to-next-to-leading order or by resumming soft and Coulomb logarithms up to next-to-next-to-leading logarithmic accuracy. The program is very flexible in that it allows the user to chose the various parameters of the calculation, like the top-quark mass, the centre-of-mass energy, and the PDF set.


The program can be downloaded from the TOPIXS webpage.
