       | There is a very strong experimental support for the "old" Higgs
       | Boson discovered in 2012 that has a mass of 125Gev, and there is
       | some recent weak experimental support for another "new" Higgs
       | Boson with a mass of 95GeV. (For comparison, the mass of a proton
       | is ~0.9GeV.)
       | 
       | In this preprint, they propose that there is a family of tree
       | Higgs Bosons. The "old" one, the "new" one and a third one yet to
       | be detected. The structure of the family forces some of the
       | properties of the bosons and how they interact with the other
       | particles.
       | 
       | The hard part is tweaking the properties of the family of Higgs
       | Bosons so they predict the results of the experiments where the
       | 125GeV and 95GeV are seen, but they don't cause weird results in
       | all the other thousands of experiments where the Higgs Bosons
       | have a negligible effect.
