“…The same can be said in the case of double Higgs production qq ′ → HHqq ′ , and in this paper we will implement the NLO QCD corrections to this process in the structure function approach. The NNLO corrections in this approach turn out to be negligibly small for single Higgs production [53,54] and we will thus ignore them for double Higgs production.…”

“…This is justified by the kinematics of the process with two widely separated quark jets of high invariant mass and by the color flow of the process. This leads to the structure function approach that has been applied with success to calculate the QCD corrections in the vector boson fusion production of a single Higgs boson [50][51][52][53][54]. Generic diagrams contributing at NLO QCD order are shown in figure 2.…”

Now that the Higgs boson has been observed by the ATLAS and CMS experiments at the LHC, the next important step would be to measure accurately its properties to establish the details of the electroweak symmetry breaking mechanism. Among the measurements which need to be performed, the determination of the Higgs self-coupling in processes where the Higgs boson is produced in pairs is of utmost importance. In this paper, we discuss the various processes which allow for the measurement of the trilinear Higgs coupling: double Higgs production in gluon fusion, vector boson fusion, double Higgs-strahlung and associated production with a top quark pair. We first evaluate the production cross sections for these processes at the LHC with center-of-mass energies ranging from the present √ s = 8 TeV to √ s = 100 TeV, and discuss their sensitivity to the trilinear Higgs coupling. We include the various higher order QCD radiative corrections, at next-to-leading order for gluon and vector boson fusion and at next-to-next-to-leading order for associated double Higgs production with a gauge boson. The theoretical uncertainties on these cross sections are estimated. Finally, we discuss the various channels which could allow for the detection of the double Higgs production signal at the LHC and estimate their potential to probe the trilinear Higgs coupling.

“…The neglected SQL type contributions in Fig.4 do not represent a class of infrared safe diagrams. However as shown in [13] their impact is small enough not to produce a significant deterioration of the VBF signal. Also, these color exchange effects are, by our definition, no VBF processes.…”

“…Furthermore it provides a clean experimental signature: it usually consists of two almost back to back hard tagging jets (generally with an invariant mass bigger than 600 GeV and a pseudo-rapidity separation between them Δη > 4) and the Higgs decay is confined in the central rapidity region. Imposing these constraints to the invariant mass and the rapidity of the jets as additional cuts (usually called VBF cuts) one reaches an impressive improvement of the signal-to-background ratio [13].…”

We present a phenomenological study for the production of the Higgs boson at next-to-next-to-leading order (NNLO) in QCD via the vector boson fusion (VBF) process. After a general discussion about the different production channels of the Higgs, we show results for hadron colliders like LHC and Tevatron in VBF. The theoretical predictions are obtained using the structure function approach. This approximation turns out to be more accurate than the precision to which the VBF Higgs production channel can be considered a well defined process by itself and the theoretical uncertainty are of the order of 1-2%. The uncertainties due to parton distributions are also discussed and are estimated to be at the same level.

“…The impact of EW corrections significantly depends on the Higgs boson mass and for a not too heavy Higgs boson is negative and tends to compensate the positive effect of QCD corrections. Other refinements of the vector boson fusion cross section include interference contributions with gluon fusion [45][46][47] and gluon induced terms [48]. These contributions are well below the percent level.…”
