Extensions of the Standard Model including Higgs doublets giving mass to neutrinos with Yukawa couplings comparable to the ones of electrically charged fundamental fermions offer the possibility of low energy tests due to the small vacuum expectation value of a component of the added Higgs doublet. We discuss the possibility of modulating the neutrino mass with properly designed electroweak and thermal cavities. Although the estimate of the effect precludes any positive detection in the foreseeable future, this discussion should also further motivate the development of high-intensity, pulsed, low-energy, monoenergetic neutrino beams.
Quintard et al. (Fri,) studied this question.
