摘要：

We explain excess events near the endpoints of the double beta decay (betabeta) spectra of several elements, using the neutrinoless emission of massless Goldstone bosons. Models with scalars carrying lepton number - 2 are proposed for this purpose so that ordinary neutrinoless betabeta is forbidden, and we can raise the scale of global symmetry breaking above the 10 keV scale needed for observable emission of conventional majorons in betabeta. The electron spectrum has a different shape, and the rate depends on different nuclear matrix elements, than for the emission of ordinary majorons.
