Four leptons final states from γγ fusion
I present a systematic study of all possible four leptons final states from γγ collisions. It is given a detailed account of fermion masses effects which are sizable since several collinear and t channel enancements occur. The effects of angular cuts on the final charged leptons are also discussed. To perform the computation I have used the recently developed ALPHA algorithm (and the resulting ...
متن کاملTriple Vector Boson Processes in γγ Colliders
We study the production of three gauge bosons at the next generation of linear ee colliders operating in the γγ mode. The processes γγ → WWV (V = Z, or γ) can provide direct information about the quartic gauge-boson couplings. We analyze the total cross section as well as several dynamical distributions of the final state particles including the effect of kinematical cuts. We find out that a li...
متن کاملHiggs Pair Production via Vector Boson Fusion at the LHC
The measurement of Higgs pair production will be one of the cornerstones of the LHC physics program in the coming years, with the upcoming high-energy and high-luminosity phase. The Vector Boson Fusion (VBF) production channel probes directly the coupling of new physics and of Higgs to gauge bosons, in addition to reducing background contribution. The production via VBF of an heavy object on-sh...
متن کاملbb̄ final states in Higgs Production via Weak Boson Fusion at the LHC 1
We present a study of the Higgs production at the LHC via Weak Boson Fusion, with the Higgs boson decaying into a bb̄ pair. A detailed partonic LO calculation of all the potential backgrounds is performed. We conclude that this channel for Higgs production can be extracted from the backgrounds, and present our estimates of the accuracy in the determination of the Hbb̄ Yukawa coupling. PACS: 12.15...
متن کاملAnomalous Higgs boson couplings in vector boson fusion at the CERN LHC
Deviations from SM expectations in the Higgs sector can be parameterized by an effective Lagrangian. The corresponding anomalous couplings have been implemented in a Monte Carlo program for Higgs production in vector boson fusion, at NLO QCD accuracy. It allows to study anomalous coupling effects for production and decay of the Higgs boson. We analyze deviations allowed by LEP data and study a ...
