The HWZ sum rule needs a Sumino mechanism

By "the HWZ sum rule", I mean the Dharwadker-Khachatryan formula that predicted the Higgs mass. (Perhaps we should call it the Dharwadker-Khachatryan sum rule.)

By a "Sumino mechanism", I mean something like Yukinari Sumino's mechanism which allows the Koide relation to be exact within experimental limits, despite the running of the masses.

This thought was prompted by Lykken's talk, mentioned in the previous post, in which a dark matter scalar controls the running of the Higgs mass. Perhaps some version of this model can also protect the DK formula from quantum corrections.

  1. A strange obscure paper: "S-matrix bootstrap of a scalar Higgs boson". It constructs scattering amplitudes for W, Z, and H according to some bootstrap principle, and the claim is that the Higgs mass is almost exactly 2 "W,Z masses" - where for some reasons W and Z masses have been approximated as 85 GeV.

    Two times that is nothing like 125 GeV. But 125 GeV is sort of like 3/2 times that. So I wonder if some revised version of this calculation is relevant.
