无中微子双β衰变对确定中微子质量具有重要意义。通过相空间因子的计算相结合的微观相互作用玻色子模型的框架内的核矩阵元的计算,我们设置的平均轻中微子质量和平均逆重中微子质量(味道违反参数)的限制。
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).
