Higgs to 3 parton amplitude and the Maximal Transcendental Principle Study the properties of Higgs boson is one of the major tasks of LHC and future CEPC. In LHC,Higgs can be produced by the fusion of gluons and quarks.Higgs to 3 parton amplitudes are very important to understand the LHC data. The maximally transcendental principle:the maximal transcendental part of N=4 SYM and QCD amplitudes are the same. N=4 SYM 2 QCD An "easy"N=4 computation gives information for the“difficult'”QCD amplitude! 5Higgs to 3 parton amplitude and the Maximal Transcendental Principle 5 The maximally transcendental principle: the maximal transcendental part of N=4 SYM and QCD amplitudes are the same.
