结果表明，规范理论对无中微子双确保数学衰变[${(\ensuremath{\beta}\ensuremath{\beta})}_{0\ensuremath{\nu}}$]的贡献没有被标准的参数化所涵盖。虽然它们可能很小，但它们的存在引发了一个问题，即${(\ensuremath{\beta}\ensuremath{\beta})}_{0\ensuremath{\nu}}$的观测是否意味着存在一个表示中微子的马约拉纳质量项。对于“自然”规范理论，我们认为情况确实如此。
It is shown that gauge theories give contributions to neutrinoless double-$\ensuremath{\beta}$ decay [${(\ensuremath{\beta}\ensuremath{\beta})}_{0\ensuremath{\nu}}$] which are not covered by the standard parametrizations. While probably small, their existence raises the question of whether the observation of ${(\ensuremath{\beta}\ensuremath{\beta})}_{0\ensuremath{\nu}}$ implies the existence of a Majorana mass term for the neutrino. For a "natural" gauge theory we argue that this is indeed the case.
