Field theory of massive vector bosons in a model with spontaneously broken symmetry

Journal Article · · Phys. Rev., D; (United States)
We study the spectrum of particle states for a charged scalar field interacting with an electromagnetic field in the Lorentz gauge. The Lagrangian contains the quartic self-coupling and imaginary-mass terms that give the scalar field a nonvanishing vacuum expectation value, and the symmetry of the model is spontaneously broken. We identify the massive vector boson and demonstrate that our identification is consistent by showing that the transverse and zero-helicity modes transform correctly among themselves in a Lorentz transformation. We show that each of the helicity modes obeys the Gupta-Bleuler subsidiary condition. We identify the Proca field contained in the theory.
