The Seesaw Mechanism and the Structure of Spacetime above the Electroweak Scale

Authors: Ervin Goldfain

According to the seesaw mechanism, neutrino masses arise from the existence of heavy Majorana neutrinos postulated to emerge near the grand unification scale (GUT) of about 10^16 GeV. Despite its theoretical appeal, this scenario involves either physics at inaccessible scales or tuning the Yukawa couplings to un-naturally low values. Our work sidesteps the seesaw mechanism and shows that neutrino masses follow from placing the Standard Model on a spacetime support equipped with arbitrarily small deviations from four dimensions.
