Lepton number violation in top-color assisted technicolor

We calculate the rates for lepton number violating processes via the exchange of the $Z^{\prime }$ boson occurring in top-color assisted technicolor. We find that $\mu -e$ conversion in nuclei is about an order of magnitude better than $\overrightarrow{\mu }3e$ for constraining the magnitudes of the lepton mixing angles. The decay $\overrightarrow{\mu }e\gamma$ yields much weaker bounds. The current experimental limits allow for a mass of the new gauge boson around $1\mathrm{TeV}$ and the magnitudes of the mixing angles turn out to lie roughly between the analogous elements of the CKM matrix and its square root.
