48 An Introduction to the Standard Model
The theory of fundamental particles and their non-gravitational interactions is encapsulated by an extremely successful quantum field theory known as the Standard Model. This quantum field theory is determined by a particular set of quantum fields and a particular Hamiltonian, which we will outline in this chapter. It is an interacting quantum field theory, not solvable by the methods we have seen so far. In the non-interacting approximation, it includes just the sorts of free quantum field theories that we have studied in earlier chapters. This chapter gives only a very brief sketch of the definition of the theory, for details one needs to consult a conventional particle physics textbook.
After outlining the basic structures of the Standard Model, we will indicate the major issues that it does not address, issues that one might hope will someday find a resolution through a better understanding of the mathematical structures that underlie this particular example of a quantum field theory.
