Higgs production
Web10 de mar. de 2011 · Abstract. We analyze the production of Higgs particles at the early stage of the CERN large Hadron Collider with a 7 TeV center of mass energy (lHC). We first consider the case of the Standard Model Higgs boson that is mainly produced in the gluon-gluon fusion channel and to be detected in its decays into electroweak gauge bosons, gg … 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.

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 ...
