WebThe fermions are the building blocks of matter. There are 12 fermions, split into six quarks and six leptons. Of the familiar particles that make up the atom, the electron is a lepton. However, protons and neutrons are not part of the Standard Model because they are bigger particles made out of quarks. WebThe Higgs boson, h(x), is a real scalar ﬁeld. It is not charged under electromagnetism (it can’t be, since it is real). Its couplings to other ﬁelds can be worked out by replacing v with v + h in our previous expressions.
