“…In Higgs-boson studies [11][12][13][14][15][16], W + W − production plays an important role as irreducible background in the H → W + W − channel. Such measurements are mostly based on final states with two leptons and two neutrinos, which provide a clean experimental signature, but do not allow for a full reconstruction of the H → W + W − resonance.…”

We consider QCD radiative corrections to W + W − production at the LHC and present the first fully differential predictions for this process at next-to-next-to-leading order (NNLO) in perturbation theory. Our computation consistently includes the leptonic decays of the W bosons, taking into account spin correlations, off-shell effects and nonresonant contributions. Detailed predictions are presented for the different-flavour channel pp → µ + e − ν µνe + X at √ s = 8 and 13 TeV. In particular, we discuss fiducial cross sections and distributions in the presence of standard selection cuts used in experimental W + W − and H → W + W − analyses at the LHC. The inclusive W + W − cross section receives large NNLO corrections, and, due to the presence of a jet veto, typical fiducial cuts have a sizeable influence on the behaviour of the perturbative expansion. The availability of differential NNLO predictions, both for inclusive and fiducial observables, will play an important role in the rich physics programme that is based on precision studies of W + W − signatures at the LHC.

“…It is worth noting that less precise measurements from other decay channels, such as H → W W ( * ) 26,27 or H → ττ, 29 are in agreement with the determination from H → γγ and H → ZZ ( * ) → llll, within their uncertainties, which are comparably larger.…”

“…In both these final states it is possible to perform a precise measurement of all particles in the decay, leading to an expected relative mass resolution for the Higgs boson between 1 and 2%. [22][23][24][25] [26][27][28][29]34,35 An excellent experimental resolution can also be achieved from the measurement of the H → µµ decay, once there is enough data to observe that decay.…”

This chapter presents an overview of the measured properties of the Higgs boson discovered in 2012 by the ATLAS and CMS collaborations at the CERN LHC. Searches for deviations from the properties predicted by the standard theory are also summarised. The present status corresponds to the combined analysis of the full Run 1 data sets of collisions collected at centre-of-mass energies of 7 and 8 TeV.

“…Jets are clustered from partons using the anti-k T algorithm [87] with a cone radius of R = 0.4. The choice of cuts is adopted from the cut-based VBF category of the H → W W study of ATLAS [88]. The corresponding CMS analysis [89] uses very similar values.…”
