Abstract

Neutrinoless double-β decay is of fundamental importance for the determining neutrino mass. By combining a calculation of nuclear matrix elements within the framework of the microscopic interacting boson model with an improved calculation of phase space factors, we set limits on the average light neutrino mass and on the average inverse heavy neutrino mass (flavor-violating parameter).

摘要

中微子无中微子双β衰变对于确定中微子质量具有根本重要性。通过在微观相互作用玻色子模型框架内结合核矩阵元素的计算以及改进的相空间因子计算，我们对平均轻中微子质量和平均反重中微子质量（违反味道参数）设置了限制。
