Higgs boson production in association with three jets via gluon fusion at the LHC: Gluonic contributions
نویسنده
چکیده
Higgs production in association with three jets via gluon fusion (GF) is an important channel for the measurement of the CP-properties of the Higgs particle at the LHC. In this letter, we go beyond the heavy top effective theory approximation and include at LO the full mass dependence of the topand bottom-quark contributions. We consider the dominant sub-channel gg → Hggg which involves the manipulation of massive rank-5 hexagon integrals. Furthermore, we present results for several differential distributions and show deviations from the effective theory as large as 100% at high pT for light Higgs masses.

Higgs plus two jet production via gluon fusion as a signal at the CERN LHC
Higgs boson production in association with two tagging jets will be mediated by electroweak vector boson fusion and by gluon fusion processes at the CERN LHC. The characteristic distributions for the gluon fusion process are analyzed for the H → W+W− signal at mH = 160 GeV, with subsequent leptonic decay of the W -pair. The dominant backgrounds from top-quark pair production, WWjj production an...
متن کاملHiggs production plus two jets at hadron colliders
In this talk we present a calculation of Higgs production via gluon fusion in association with two jets, including the full top-quark mass dependence, and compare it to the large top-mass limit. We find that the large top-mass limit is a good approximation as long as the Higgs mass is smaller than the top quark pair mass, and the jet transverse energies are smaller than the top mass. In additio...

The search for di-Higgs production at the LHC in order to set limits on the Higgs trilinear coupling and constraints on new physics is one of the main motivations for the LHC high-luminosity phase. Recent experimental analyses suggest that such analyses will only be successful if information from a range of channels is included. We therefore investigate di-Higgs production in association with t...

We present phenomenological results for the production of a Higgs boson in association with two jets at the LHC. The calculation is performed in the limit of large top mass and is accurate to next-to-leading order in the strong coupling, i.e. O(αs).
متن کاملElectroweak Higgs plus Three Jet Production at NLO QCD
Higgs production via vector boson fusion (VBF) is an essential channel at the LHC for disentangling the Higgs boson’s coupling to fermions and gauge bosons. The observation of two tagging jets is crucial to reduce the backgrounds. Furthermore, the possibility to identify Higgs production via VBF is enhanced by being able to increase the signal to background ratio by vetoing additional soft radi...
