Verifiable Model of Neutrino Masses from Large Extra Dimensions
Verifiable Model of Neutrino Masses from Large Extra Dimensions
We propose a new scenario of neutrino masses with a Higgs triplet $({\ensuremath{\xi}}^{++},{\ensuremath{\xi}}^{+},{\ensuremath{\xi}}^{0})$ in a theory of large extra dimensions. Lepton number violation in a distant brane acts as the source of a very small trilinear coupling of $\ensuremath{\xi}$ to the standard Higgs doublet in our brane. Small realistic Majorana …
