The fellow alum who was mentioned in my previous post, just replied as follows. As I recall, he was a Physics major (mine was Math):
I offer no comment about Feynman and the Higgs boson. However, permit me to note that either of the 2 last links in my signature (immediately below) points to work that provides a technique for cataloging types of elementary particles. There is a place (4w5) in the catalog for Higgs-like particles. The catalog includes categories for all known elementary-force-mediating bosons, a possible decomposition of the strong interaction, and more.
To the extent you are interested, perhaps you will read “Physics 642b.” It is written so that someone with understanding of logarithms and exponentials can (hopefully) learn much of what’s in the book. Permit me to attach two extracts from the book. The first extract makes two references to Feynman.
Here are the cited links:
