论文摘要
我们使用手性相互作用和几种{\ em ab libio}方法来计算核矩阵元素(NMES),以在一系列的同位素中以地面状态到地面双重gamow teller转变,并探索这些Nmes与这些NMES与中性beta beta deble beta deble beta double beta deble by supers a Lightale seplact a Lightale seplace a Lightale selectale seleverna seletrinlo产生的相关性。当同时考虑{\ em ab intib}计算的所有同胞持续和同义变化的转变时,相关性很强。但是,对于与实验相关的变化转变,相关性较弱,可能对减少NME的不确定性没有帮助,以减少中微子双β衰减的不确定性。
We use chiral interactions and several {\em ab initio} methods to compute the nuclear matrix elements (NMEs) for ground-state to ground-state double Gamow-Teller transitions in a range of isotopes, and explore the correlation of these NMEs with those for neutrinoless double beta decay produced by the exchange of a light Majorana neutrino. When all the NMEs of both isospin-conserving and isospin-changing transitions from the {\em ab initio} calculations are considered, the correlation is strong. For the experimentally relevant isospin-changing transitions by themselves, however, the correlation is weaker and may not be helpful for reducing the uncertainty in the NMEs for neutrinoless double-beta decay.
