右手中微子磁矩

Right-handed neutrino magnetic moments

Alberto Aparici, Kyungwook Kim, Arcadi Santamaria, José Wudka

摘要:

我们考虑了仅使用标准模型场加上右手中微子就可以建立的最一般的五维有效拉格朗日量,并发现存在一个提供电弱矩的项(即,耦合到Z和光子)的右手中微子。该术语先前在文献中没有描述过。我们讨论了它的现象学和边界,可以从LEP的结果和红巨星和超新星的冷却过程的观察。

英文摘要:

We consider the most general dimension-five effective Lagrangian that can be built using only Standard Model fields plus right-handed neutrinos, and find that there exists a term that provides electroweak moments (i.e., couplings to the Z and photon) for the right-handed neutrinos. Such term has not been described previously in the literature. We discuss its phenomenology and the bounds that can be derived from LEP results and from the observation of the cooling process of red giants and supernovae.
