What Is Gauge Theory?,between the form of an interaction and the symmetries of the theory. In this chapter, we introduce the general notion of gauge field and gauge theory, and show that one possible answer to the question above is the so-called “gauge principle”. In the following, we shall survey the formalism needed to

Spontaneous Symmetry Breaking,ase, a quantum of the gauge field corresponding to the broken or hidden symmetry acquires mass, in contrast to the photon. In this chapter, we will discuss a mechanism whereby the symmetry in the Lagrangian is broken.

,Becchi–Rouet–Stora Transformations,or the gauge field and the fermion field. However, in order to quantize these fields, we need to introduce the gauge-fixing term and the Faddeev–Popov ghost term. Consequently, the invariance under the local gauge transformation is broken. However, a new global invariance shows up in its place. This
