Higgs-mass predictions

In 2007, Thomas Schücker wrote an amusing simple preprint that collects dozens of predictions for the Higgs boson masses:

Its v5 version was just posted. The guesses go from 109+-12 GeV to 760+-21 GeV, plus two unconventional theories with 1900 GeV and 10^{18} GeV.

Well, I think that there are so many comparably likely models - most of which contain continuous parameters whose values aren't calculable right now - that the whole interval is covered almost uniformly. But yes, I do think it's more likely than not that the Higgs boson mass is between 114 GeV and 130 GeV.

Once the Higgs is discovered, which may take a year or years, you can check whether the mass helps you to find the very right model. However, I doubt that the right one actually appears in this "yellow book" which has been compiled in a somewhat chaotic fashion. ;-)

Of course, most of the models that are included are supersymmetric which is good but it's far from enough for them to be right.

  1. The paper omits the prediction made by season 4 of the Canadian TV series LEXX, that the mass is 131.313... GeV. :-)
