Web7 de ago. de 2024 · A study of the charge conjugation and parity (CP) properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are identified via the diphoton decay channel (H→γγ), and their production in association with a top quark pair (tt[over ¯]H) or single top quark (tH) is … Web4 de jul. de 2024 · The “Higgs mechanism,” which consists of the Higgs field and its corresponding Higgs boson, is said to give mass to elementary particles. By “mass” we mean the inertial mass, which resists when we try to accelerate an object, rather than the gravitational mass, which is sensitive to gravity. WebIn addition to the measurement of the mass of the Higgs, the data also reveals a tantalizing hint of a significantly enhanced diphoton signal rate, 1.56±0.43 and 1.9±0.5 times of the SM prediction in the CMS and ATLAS experiments, respectively. We demonstrate that such an enhancement can be accommodated in this MSSM extension. can i purchase homeowners insurance online
