Quantum Field Theory

Quantum field theory is the framework in which the regnant theories of the electroweak and strong interactions, which together form the standard model, are formulated. Quantum electrodynamics (QED), besides providing a complete foundation for atomic physics and chemistry, has supported calculations of physical quantities with unparalleled precision. The experimentally measured value of the magnetic dipole moment of the muon, $${\left({{g_\mu } - 2} \right)_{\exp }} = 233\,184\,600\,\left({1680} \right) \times {10^{ - 11}},$$ for example, should be compared with the theoretical prediction $${\left({{g_\mu } - 2} \right)_{{\rm{theor}}}} = 233\,183\,478\,\left( {308} \right) \times {10^{ - 11}}$$ (see the chapter by Hughes and Kinoshita on pp. 223-233 in this book).
