Enhanced electric dipole moment of the muon in the presence of large neutrino mixing
Abstract
The electric dipole moment of the muon (dmu) is evaluated in supersymmetric models with nonzero neutrino masses and large neutrino mixing arising from the seesaw mechanism. It is found that if the seesaw mechanism is embedded in the framework of a left-right symmetric gauge structure, the interactions responsible for the right-handed neutrino Majorana masses lead to an enhancement in dmu. We find dmu as large as 5. 10-23 ecm with a correlated value of (g-2) = 13. 10-10, even for low values of tan beta. This should provide a strong motivation for improving the edm of the muon to the level of 10-24 ecm as has recently been proposed.
