H + 2 jets via gluon fusion
نویسنده
چکیده
Real emission corrections to gg→H, which lead to H +2 jet events, are calculated at order αs. Contributions include top-quark triangles, boxes and pentagon diagrams and are evaluated analytically for arbitrary top mass mt. This new source of H +2 jet events is compared to the weak-boson fusion cross section for a range of Higgs boson masses. The heavy top-mass approximation appears to work well for intermediate Higgs-boson masses, provided that the transverse momenta of the final-state partons are smaller than the top-quark mass.

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 کاملThe high - energy limit of H + 2 jet production via gluon fusion
At the Large Hadron Collider (LHC), the main production channels of a Higgs boson are gluon fusion and weak-boson fusion (WBF) [1, 2]. The WBF process, qq → qqH , occurs through the exchange of a W or a Z boson in the t channel, and is characterized by the production of two forward quark jets [3]. Even though it is smaller than the gluon fusion channel by about a factor of 5 for an intermediate...
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...

Higgs boson production in association with two tagging jets will be mediated by electroweak vector boson fusion and by gluon fusion. For the gluon fusion process, analysis of the azimuthal angle correlations of the two jets provides for a direct measurement of the CP-nature of the Htt Yukawa coupling which is responsible for the effective Hgg vertex.

متن کاملHiggs Boson Production in Association with Multiple Hard Jets
We elucidate a new technique for estimating the production of multiple (at least two) hard jets in Higgs production via gluon-gluon fusion. The approach is based upon high energy factorisation, with the region of applicability extended by constraints on the analytic behaviour of the scattering amplitudes stemming from known all-order results. The method approximates both real and virtual correc...
