论文摘要
我们布置了一种新型的形式主义，以将isospin对称性破坏校正与超纯核β衰减的速率，$δ_\ text {c} $连接到可以通过实验访问的Electroweak核半径的敏感组合。我们在超允许的衰减图中个性化过渡，即使以中等的精度，稳定女儿的中子皮肤的测量也可能已经有助于区分用于计算$δ_\ text {c} $的模型。我们审查现有的实验情况，并与现有和未来的实验计划建立联系。
We lay out a novel formalism to connect the isospin-symmetry breaking correction to the rates of superallowed nuclear beta decays, $δ_\text{C}$, to the isospin-breaking sensitive combinations of electroweak nuclear radii that can be accessed experimentally. We individuate transitions in the superallowed decay chart where a measurement of the neutron skin of a stable daughter even at a moderate precision could already help discriminating between models used to compute $δ_\text{C}$. We review the existing experimental situation and make connection to the existing and future experimental programs.
