I am reading a book called "Gauge Fields, Knots and Gravity" by Baez et. al.
In the first chapter, the authors explains that there are three generations of charged particles:
- First: electrons, electron neutrino, up/down quarks
- Second: muon, muon neutrino, charm/strange quarks
- Third: tau, tau neutrino, top/bottom quarks
Afterwards the author mentions that another charged particle is rumored to exist called the Higgs Boson that is neither a quark or a lepton and explains the relation between EM and the weak force. This was written dated 1994.
Now that the Higgs Boson has been discovered, I wonder if it fits anywhere in the "3-generation" scheme provided by the author? If the book was to be updated now, where would Higgs Boson lie? As some sort of 4th generation particle?
