Large Higgs mass and μ-e universality

In the limit of very large Higgs mass the Weinberg model becomes non-renormalizable, and this, in principle, provides for an upper limit on the Higgs mass. In actual fact, without further speculation, no useful limit emerges. Instead one is led to speculations on direct lepton hadron interactions violating μ-e universality. The experimental evidence on this point is considered. (Auth.)
