Loop effects on the Higgs decay widths in extended Higgs models
WebThe fermions are the building blocks of matter. There are 12 fermions, split into six quarks and six leptons. Of the familiar particles that make up the atom, the electron is a lepton. However, protons and neutrons are not part of the Standard Model because they are bigger particles made out of quarks. Web5 de mar. de 2024 · Abstract: In order to identify the Higgs sector using future precision data, we calculate the partial decay widths of the discovered Higgs boson with the mass of 125 GeV into fermion pairs and gauge-boson pairs with one-loop electroweak and one-loop QCD corrections in various extended Higgs models, such as the Higgs singlet model … early voting walpole ma
Higgs couplings and fermion masses - Physics Stack Exchange
Web4 de jul. de 2024 · In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts. Ten years later, and with the ... In particle physics, a fermion is a particle that follows Fermi–Dirac statistics. Generally, it has a half-odd-integer spin: spin 1/2, spin 3/2, etc. In addition, these particles obey the Pauli exclusion principle. Fermions include all quarks and leptons and all composite particles made of an odd number of these, such as all baryons and many atoms and nuclei. Fermions differ from bosons, which obey B… WebHiggs boson is produced in association with a heavy vector boson, V, namely a W or a Z boson, identified via its leptonic decay. Requiring the presence of additional leptons with high transverse momentum provides an e˙ective handle to reduce the QCD background. The Higgs boson candidate is reconstructed from two early voting wagga
