Neutrino mass, bulk majoron and neutrinoless double beta decay
Abstract
A new economical model for neutrino masses is proposed in the context of the brane-bulk scenarios for particle physics, where the global /B-/L symmetry of the standard model is broken spontaneously by a gauge singlet Higgs field in the bulk. This leads to a bulk singlet majoron whose Kaluza-Klein excitations may make it visible in neutrinoless double beta decay for some parameter range if the string scale is close to a TeV.
