摘要:

在准粒子无规相位近似下估计了无中微子双β衰变的核矩阵元的方差和协方差。结果表明,关联NME不确定度在不同核的无中微子双β衰变速率的比较中起着重要作用,它们与重建的Majorana中微子质量的不确定度是简并的.

英文摘要:

The variances and covariances associated to the nuclear matrix elements (NME) of neutrinoless double beta decay are estimated within the quasiparticle random phase approximation (QRPA). It is shown that correlated NME uncertainties play an important role in the comparison of neutrinoless double beta decay rates for different nuclei, and that they are degenerate with the uncertainty in the reconstructed Majorana neutrino mass.
