Vector bosons are characteristically studied using the YangLee propagator, renormalization, and ξlimiting techniques. Although renormalization is the standard method for solving all renormalization problems, it is not accepted by all physicists, and even Feynman referred to it as “sweeping the infinities under the rug.” As an alternative to renormalization, this calculation attempts to solve for the vertex correction term by modifying the usual YangLee vector boson propagator by a normalization term. While we do not claim that this normalization term is unique or even covariant, it does show that it is possible to calculate the vertex correction without relying upon regularization or renormalization. Since the standard model relies heavily on renormalization and perturbative techniques, a method that uses neither technique allows for new thinking about vector bosons in particular and particle physics in general.
