Quantum corrections to the generalized Proca theory via a matter field

Quantum corrections to the generalized Proca theory via a matter field

We study the quantum corrections to the generalized Proca theory via matter loops. We consider two types of interactions, linear and nonlinear in the vector field. Calculating the one-loop correction to the vector field propagator, three- and four-point functions, we show that the non-linear interac...
