关于中微子质量的一个新建议|V(ud)|测量

A New Proposal for Neutrino Mass and |V(ud)| Measurements

Akihiro Matsuzaki, Hidekazu Tanaka

摘要:

介绍了一种新的中微子绝对质量标度的测量方法。它使用了一个宏观质量的氚源。我们解释了中微子质量可以通过标度源的初终态质量差及其热值来测量。该方法不受电子能量分辨极限和统计误差的限制。我们估计测量中微子质量所需的精度。我们还报告,CKM矩阵的{u,d}分量,|V(ud)|作为这项工作的应用,可以在10^-6的精度下确定。

英文摘要:

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.
