关于带Majorana质量项的标准模型拉格朗日量的解

On solutions of the standard-model Lagrangian with a Majorana mass term

R. Plaga

摘要:

证明了中微子的带马约拉纳质量项的标准模型拉格朗日量不存在非平凡解。因为一般认为标准模型能正确描述中微子的规范相互作用,所以马约拉纳质量项必须为零,因此不能产生无中微子的双β衰变。更一般地说,具有标准模型规范相互作用的中微子不可能是马约拉纳场。分析了这一结论未能较早得出的历史原因。

英文摘要:

It is demonstrated that the standard-model Lagrangian with a Majorana mass term for the neutrino admits no non-trivial solution. Because the standard model is generally believed to describe the gauge interactions of neutrinos correctly, the Majorana mass term must vanish and thus cannot enable neutrino-less double beta decay. More generally, neutrinos with standard-model gauge interactions cannot be Majorana fields. Historical reasons why this conclusion has not been drawn earlier are analyzed.
