2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/190339A new economical model for neutrino masses is proposed in the context of brane bulk scenarios for particle physics, where 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 majoron whose KK excitations may make it visible if neutrinoless double beta decay if the string scale is close to a TeV. It also leads to neutron-anti-neutron oscillation process with transition times which can be in the range accessible to proposed experiments.7 pages, one figure embedded; UMD-PP-00-099High Energy Physics - Phenomenologytext
