==Quantum Field Theory==
Nice article on quantum field theory. Btw, I have a question. I often hear people say that the Higgs field accounts for why particles have mass. But I was under the impression that the Higgs field was only introduced to give mass to gauge fields by spontaneously breaking the gauge symmetry (so that, loosely speaking, the gauge field "eats" a Goldstone boson). As far a I can tell, it looks like the mass of leptons is simply inserted into the Lagrangian and plays no role in the Higgs mechanism. What am I missing?--[[User:Lemonpeel|Lemonpeel]] 11:37, 15 June 2009 (EDT)
