Web8 de mar. de 2024 · Higgs self-coupling. The measurement of the Higgs particle mass at the LHC has made the determination of the value of the Higgs self-coupling possible: with M H ≈ 125 GeV, one gets λ ≈ 1 / 8. Does this particular value imply anything special for the Standard Model, except that now books can be filled with the values of M H and λ?
