What is so special about the Standard Model? Small representations.

Now it seems that the Standard Model gets more and more supported without yet convincing signs of new physics, so one may with increased strength ask: Why is just the a priori not so obvious Standard Model being selected by Nature? Don Bennett and I started by asking for a quantity depending on the gauge gruop which would be maximal on the Standard Model Group. We found a quantity which is essentially the ratio of the quadratic Casimir for the adjoint representation relative to the quadratic Casimir for the “smallest” faithful representation. Essentially the same maximization principle seems also to deliver the space-time dimension and the representation for the Higgs field. Taking into account the requirements of no anomalies, it is also very close at least to tell what Weyl field representations one shall find. So approximately the whole Standard Model except the number of families come out from such a really “small representation” principle!
