Findings

Neutrino mass can be measured without electron energy resolution limits.

Estimated accuracy for |V(ud)| determination is 10^-6.

Method provides a new avenue for fundamental particle property measurements.

Abstract

We introduce a new method to detect the absolute neutrino mass scale. It uses a macroscopic mass of tritium source. We explain that the neutrino mass can be measured by scaling the mass difference of the source between initial and final state, and its heat value. This method is free from the electron energy resolution limit and the statistical error. We estimate the required accuracy to measure the neutrino mass. We also report that the {u,d} component of the CKM matrix, |V(ud)| may be determined in 10^-6 accuracy as an application of this work.
