Web14 de mar. de 2024 · Higgs boson production cross sections measured in the ATLAS experiment [ 5] (signal strengths measured in the CMS experiment [ 6 ]) after a combination of seven decay channels assuming corresponding BR are from the SM. Full size image Fig. 9 Particle physicists study matter made from fundamental particles whose interactions are mediated by exchange particles – gauge bosons – acting as force carriers. At the beginning of the 1960s a number of these particles had been discovered or proposed, along with theories suggesting how they relate to each other, some of which had already been reformulated as field theories in which t…
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 … Web3 de jan. de 2024 · Combined measurements of Higgs boson production cross sections and branching fractions are presented. The combination is based on the analyses of the Higgs boson decay modes H→γγ, ZZ∗, W W ∗, τ τ, b¯b, μμ, searches for decays into invisible final states, and on measurements of off-shell Higgs boson production.
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. Web1 de dez. de 2024 · The associated production of the Higgs boson with a pair of top quarks (ttH) is the rarest Higgs production mode observed so far, a hundred times smaller than the dominant Higgs boson production through the fusion of two gluons. It gives direct access to the coupling between the Higgs boson and the top quark.
