Gluon-Gluon Antenna Functions from Higgs Boson Decay
Antenna functions describe the infrared singular behaviour of colour-ordered QCD matrix elements due to the emission of unresolved partons inside an antenna formed by two hard partons. In this paper, we show that antenna functions for hard gluon-gluon pairs can be systematically derived from the effective Lagrangian describing Higgs boson decay into gluons, and compute the the infrared structur...
متن کاملHiggs-boson decay into photons
We compute the dominant two-loop electroweak correction, of O(GFM t ), to the partial width of the decay of an intermediate-mass Higgs boson into a pair of photons. We use the asymptotic-expansion technique in order to extract the leading dependence on the top-quark mass plus four expansion terms that describe the dependence on the W and Higgs-boson masses. This correction reduces the Born resu...
متن کاملAnomalous Higgs Boson Production and Decay
A non-standard symmetry breaking sector may lead to derivative couplings of the Higgs boson and thereby to anomalous interactions with the electroweak gauge bosons. In the framework of gauge-invariant effective Lagrangians the resulting changes in Higgs boson production and decay mechanisms are related to anomalous triple vector boson couplings. Using low energy constraints on the dimension-six...
متن کاملAnomalous Radiative Decay of Heavy Higgs Boson
The radiative decay width of a heavy Higgs boson H → W+W−γ for a hard photon is calculated in the Standard Model and its extension with anomalous γWW couplings. Its dependence on the Higgs mass, the two unknown anomalous couplings, and the photon energy cutoff are studied in detail. We show that this radiative decay of a heavy Higgs is not very sensitive to a wide range of the anomalous couplin...
متن کاملQuark-Gluon Antenna Functions from Neutralino Decay
The computation of exclusive QCD jet observables at higher orders requires a method for the subtraction of infrared singular configurations arising from multiple radiation of real partons. One commonly used method at next-to-leading order (NLO) is based on the antenna factorization of colour-ordered matrix elements, and uses antenna functions to subtract the real radiation singularities. Up to ...
