Web4 de ago. de 2024 · We present analytic results for the partonic cross sections for the production of a Higgs boson via the fusion of two bottom quarks at N 3 LO in QCD perturbation theory in the five-flavour scheme. We combine this perturbative result with NLO accurate predictions in the four-flavour scheme that include the full bottom quark mass … WebHiggs boson pair production is traditionally considered to be of particular interest for a measurement of the trilinear Higgs self-coupling. Yet it can offer insights into other couplings as well, since - in an effective field theory (EFT) parameterisation of potential new physics - both the production cross section and kinematical properties of the Higgs …

WebHiggs production: The left side of this Feynman diagram represents the main production mode of the Higgs boson at the LHC. The incoming particles are two gluons, one from each colliding proton. The gluons then exchange a virtual top quark, which produces a virtual top-antitop pair. This pair then annihilates to produce a real Higgs boson. Higgs ... Web10. The electron-positron pair can produce directly a Higgs boson, but this process is very suppressed, because the coupling between the leptons and the Higgs is proportional to the tiny mass m e: g H e e = − i m e v, where v ≈ 246 G e V. On the other hand, the process e + e − → H Z is more likely to happen, because the coupling between ... maytag drum roller commercial dryer

First of all, the protons circulating in the LHC have to be considered as a bag of quark and … The most common expected processes for Higgs boson production are: Gluon fusion If the collided particles are hadrons such as the proton or antiproton – as is the case in the LHC and Tevatron – then it is most likely that two of the gluons binding the hadron together collide. Ver mais The Higgs boson, sometimes called the Higgs particle, is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory. … Ver mais Evidence of the Higgs field and its properties has been extremely significant for many reasons. The importance of the Higgs boson is … Ver mais Theoretical need for the Higgs Gauge invariance is an important property of modern particle theories such as the Standard Model, partly due to its success in other areas of … Ver mais Naming Names used by physicists The name most strongly associated with the particle and field is the Higgs boson and Higgs field.
