Higgs production modes
Web1 de jul. de 2024 · All main production and decay modes have been observed by ATLAS and CMS, and the couplings to vector bosons and third-generation fermions are probed with 5 to 10% accuracy, confirming the pattern expected from the Brout–Englert–Higgs mechanism for electroweak symmetry breaking and the generation of the masses of … WebThe self-coupling of the Higgs boson is of particular interest to understand the electroweak symmetry breaking mechanism, and to constrain new physics beyond the Standard Model (SM). In that context, Higgs pair production will play a key role at the LHC Aaboud et al. ( 2024a , b , c , d , 2016 ); Aad et al. ( 2015a , b , c ); Sirunyan et al. ( 2024a , b , c , d ); …

WebIn the framework, the major Higgs boson production modes are sub-divided into different regions, or “templates". These templates are defined by certain properties of the event, such as the transverse momentum of the Higgs boson or the number of additional sprays of particles, known as jets. WebT Higgs Boson production is contaminated by many production modes other than gluon-gluon fusion, including vector boson fusion, production of a Higgs boson in association …

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.
