Right: top box diagram. If one stays with the SM parameters, the cross-section for the HH production and the kinematics of the Higgs bosons being produced is fully defined.
WebThe Circular Electron Positron Collider (CEPC) is a future Higgs factory proposed by the Chinese high energy physics community. It will operate at a center-of-mass energy of 240-250 GeV. The CEPC will accumulate an integrated luminosity of 5 ab(-1) over ten years of operation, producing one million Higgs bosons via the Higgsstrahlung and vector boson … Web27 de jan. de 2024 · The Higgs self-coupling, however, enters through loops also in single-Higgs production and indirect effects might therefore be observable, for instance as a small (< 1%) deviation in measurements of the inclusive ZH cross section. Measurements of the Higgs self-coupling exploiting the di-Higgs production process can only be …
WebThe program PPHQQ calculates the production cross section of Higgs bosons via vector boson fu-sion WW/ZZ ! h,H at hadron colliders at NLO QCD.Interferencee ectsbetweenW-andZ-boson fusion are neglected, since they are less than 1%. The program allows to calculate the total produc-tion cross section in the DIS as well as the MSbar
