Lepton flavor violation without supersymmetry

We study the lepton flavor-violating (LFV) processes mu-->egamma, mu-->3e, and mu-->e conversion in nuclei in the left-right symmetric model without supersymmetry and perform the first complete computation of the LFV branching ratios B(mu-->f) to leading nontrivial order in the ratio of left- and right-handed symmetry-breaking scales. To this order, B(mu-->egamma) and B(mu-->e) are governed by the same combination of LFV violating couplings, and their ratio is naturally of order unity. We also find B(mu-->3e)/B(mu-->e)similar to100 under slightly stronger assumptions. Existing limits on the branching ratios already substantially constrain mass splittings and/or mixings in the heavy neutrino sector. When combined with future collider studies and precision electroweak measurements, improved limits on LFV processes will test the viability of low-scale, nonsupersymmetric LFV scenarios.
