Higgs production
Web8 de mai. de 2015 · We have systematically investigated the production of a Higgs boson with a mass of about 125 GeV in the decays of supersymmetric particles within the phenomenological MSSM (pMSSM). We find regions of parameter space that are consistent with all world data and that predict a sizeable rate of anomalous Higgs, di-Higgs 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.

Web1 de jul. de 2024 · Higgs encounters Top: a candidate event recorded by ATLAS in 2024 for the associated production of a Higgs boson with a top quark pair, with the Higgs boson decaying to a photon pair. The event contains one electron candidate (green line) and two photon candidates (green towers) with a diphoton mass of 125.2 GeV. Web27 de jan. de 2024 · In Higgs-production mode the beam lifetime is limited by Bhabha scattering to about 30 minutes and therefore requires quasi-continuous injection or “top-up” as used by the B-factories. Each of the circular collider main concepts and parameters has been demonstrated in a previous machine, and thus the designs are considered mature.
Web9 de abr. de 2024 · The Higgs boson is the simplest known particle: a “ fragment of vacuum ” with no charge or spin. As with all elementary particles, it is an excitation, or quantum, of a more fundamental entity called a field – the uniquely featureless Brout–Englert–Higgs field, which fills all space uniformly. This field is understood to have come ... Web14 de jan. de 2024 · Since its discovery, the Higgs boson became a prime tool to search for physics beyond the Standard Model (SM).
