  We explore the possibility that the Higgs boson of the standard model be
actually a member of a larger family, by showing that a more elaborate internal
structure naturally arises from geometrical arguments, in the context of a
partly original handling of gauge fields which was put forward in previous
papers. A possible mechanism yielding the usual Higgs potential is proposed.
New types of point interactions, arising in particular from two-spinor index
contractions, are shown to be allowed.
