Higgs branching ratio
WebThe branching ratios B k depend on number k of succeeding decays in a decay channel. Define the branching ratios as follows B k = B γγ (2 k – 1), (2) where k = 1, 2, 3, 4, 5, 6, 7 … Web希格斯玻色子（英語： Higgs boson ）是標準模型裏的一種基本粒子，是一種玻色子，自旋為零，宇稱為正值，不帶電荷、色荷，極不穩定，生成後會立刻衰變。 希格斯玻色子是希格斯場的量子激發。 根據希格斯機制，基本粒子因與希格斯場耦合而獲得質量。 。假若希格斯玻色子被證實存在，則 ...

Web10 de ago. de 2016 · In this paper we ventured to project the 6D parameter space on the 3D space of Higgs masses to obtain the expected range of branching ratios as function of the Higgs mass for each Higgs boson. This allows us to look for the distinctive features between the NMSSM and CMSSM. WebThe branching ratios listed in Ref. [16] are B (H → eeµµ) = 5.93·10 −5 and B (H → eeee) = 3.27·10 −5 . The approximate factor of two between the two rates reflects (i) the statistical factor of...
WebThe Standard Model predicts that Higgs bosons could be formed in a number of ways, although the probability of producing a Higgs boson in any collision is always expected to be very small – for example, only one … Web9 de abr. de 2024 · An observed (expected) 95% CL upper limit on the branching ratio for this decay is set at 0.018 (0.017-0.005+0.007), assuming the Standard Model production cross-section for a 125 GeV Higgs boson.
