It is remarkable that the measured Higgs boson mass is so close to the valuewhich maximizes the Higgs decay rate to photons as predicted by the StandardModel. In this work we explore the consequences to assume that an $\sim 125$GeV Higgs boson mass is not accidental, but fixed by some fundamental principlethat enforces it to maximize its decay rate into photons. The principle ismotivated by the evidence that only a very small volume of the parameters spaceof the Standard Model, which contains their measured values, could lead to amaximal Higgs boson with that mass. If the principle actually holds, severalStandard Model features get fixed, as the number of fermion families, quarkcolors, and the CP nature of the new boson, for example. We also illustrate howsuch principle can place strong bounds on new physics scenarios as a Higgs darkportal model and a Two Higgs Doublet Model.

Is There a Hidden Principle in the Higgs Boson Decay to Photons?
