Horizontal Symmetry and Large Neutrino Magnetic Moments
Abstrak
We investigate new symmetries which decouple the mass from the magnetic moment of neutrinos and their theoretical and phenomenological implications are discussed. Our proposed model is based on 𝑆𝑈 ( 2 ) 𝐻 horizontal symmetry that can generate large neutrino transition magnetic moment without inducing unacceptably large neutrino masses. In the 𝑆𝑈 ( 2 ) 𝐻 symmetric limit, the transition magnetic moment is nonzero, while the neutrino mass vanishes. The simplification we suggest is based on the symmetry being approximate, which we also generalize to a three-family 𝑆𝑈 ( 3 ) 𝐻 -symmetry. We have also investigated a spin symmetry mechanism that can generate large 𝜇 𝜈 while keeping 𝑚 𝜈 small. This talk is based on results obtained with K.S. Babu, and Manfred Lindner and presented in hep-ph 2007.04291 [1].
