Does the new version supersede the previous version?: Yes
Nature of problem:
Calculation of hadroproduction of W bosons, with differential distributions, at next-to-next-to-leading order in the strong coupling.
Integral reduction, sector decomposition, numerical integration
Reasons for new version:
Reintroduction of W boson to FEWZ 2
Summary of revisions:
Addition of W boson production, now can run in W or Z/gamma mode. LHAPDF interface added. Large speed improvements achieved through caching repeat function calls. New observables and histograms. Improved histogram binning.
Running with all histograms on requires approx. 1 GB of disk space to store intermediate files.
2 hours to achieve NNLO precision in cross section on multicore machines, up to a few days for quality kinematic distributions. Cluster running is considerably faster.
