Nonconservation of Muon Number in a Broken SU(4) ⊗ U(1)Gauge Theory

We suggest a unified gauge theory based on a spontaneously broken SU(4) ⊗ U(1) symmetry. It is the presence of additional gauge bosons in our model which is responsible for muon-number-nonconserving processes. We have considered specifically $\mu \to e\gamma$, $\mu \to 3e$, and $\mu +\mathfrak{N}\to e+\mathfrak{N}$, and find that the last process is the most amenable to experimental detection.
