Nature of problem:
Computation of differential cross sections for inclusive production of single hadronic jets and jet pairs at next-to-leading order accuracy in perturbative quantum chromodynamics.
Upon subtraction of infrared singularities, the hard-scattering matrix elements are integrated over available phase space using an optimized VEGAS algorithm. Weighted events are generated and filled into a finely binned two-dimensional histogram, from which the final cross sections with typical experimental binning and cuts are computed by an independent analysis program.
Monte Carlo sampling of event weights is tuned automatically to get better efficiency.
Depends on details of the calculation and sought numerical accuracy. See benchmark performance in Section 4.
The tests provided take approximately 27 minutes for the jetbin run and a few seconds for jetana.
