Absolute neutrino mass and the Dirac/Majorana distinction from the weak interaction of aggregate matter
Abstract
The 2 ν -mediated force has a range of microns, well beyond the atomic scale. The effective potential is built from the t -channel absorptive part of the scattering amplitude and depends on neutrino properties on shell. We demonstrate that neutral aggregate matter has a weak charge and calculate the matrix of six coherent charges for its interaction with definite-mass neutrinos. Near the range of the potential the neutrino pair is nonrelativistic, leading to observable absolute mass and Dirac/Majorana distinction via different r -dependence and violation of the weak equivalence principle.
