Weak Interactions with Lepton-Hadron Symmetry

TLDR: In this paper, a model of weak interactions was proposed in which the currents are constructed out of four basic quark fields and interact with a charged massive vector boson, and it was shown that the leading divergences do not violate any strong-interaction symmetry.

Abstract: We propose a model of weak interactions in which the currents are constructed out of four basic quark fields and interact with a charged massive vector boson. We show, to all orders in perturbation theory, that the leading divergences do not violate any strong-interaction symmetry and the next to the leading divergences respect all observed weak-interaction selection rules. The model features a remarkable symmetry between leptons and quarks. The extension of our model to a complete Yang-Mills theory is discussed.
