We present phenomenological results for vector boson pair production at the LHC, obtained using the parton-level next-to-leading order program MCFM. We include the implementation of a new process in the code, pp → γγ, and important updates to existing processes. We incorporate fragmentation contributions in order to allow for the experimental isolation of photons in γγ, Wγ, and Zγ production and also account for gluon-gluon initial state contributions for all relevant processes. We present results for a variety of phenomenological scenarios, at the current operating energy of $ \sqrt {s} = 7 $ TeV and for the ultimate machine goal, $ \sqrt {s} = 14 $ TeV. We investigate the impact of our predictions on several important distributions that enter into searches for new physics at the LHC.

Observation of a new particle in the search for the Standard Model Higgs boson with the ATLAS detector at the LHC (2012, neutral): “[53, 117, 118], with the noticeable di ﬀ erence that an explicit calculation of the gluon-fusion process at NLO using MCFM [137] in the 2-jet category reduces the uncertainty on this non-negligible contribution to 25%.”

Les Houches 2017: Physics at TeV Colliders Standard Model Working Group Report (2017, background): “Originally computed at N2LOQCD with qT subtraction [325], it has recently been recomputed [326] using the N -jettiness subtraction implemented within MCFM.”
Search for gluino mediated bottom- and top-squark production in multijet final states in pp collisions at 8 TeV (2013, methodology): “The diboson MC distribution, given by the sum of contributions from WW, WZ, and ZZ events, is normalized to NLO using the cross section from the mcfm generator [49].”
Associated production of a Higgs boson at NNLO (2016, background): “At NLO the cross section becomes sensitive to the renormalization scale, but typically there is an accidental cancellation between the renormalization and factorization scales resulting in a weak scale dependence even at NLO [44].”

Evidence for the Higgs-boson Yukawa coupling to tau leptons with the ATLAS detector (2015, neutral): “The NLO EW corrections for VBF production depend on the pT of the Higgs bo- son, varying from a few percent at low pT to ∼ 20% at pT = 300 GeV [70].”
