双Higgs轻子最小味破坏

Two-Higgs Leptonic Minimal Flavour Violation

F. J. Botella, G. C. Branco, M. Nebot, M. N. Rebelo

摘要:

我们构建了扩展的标准模型与两个希格斯双峰,有味道改变中性流的夸克和轻子部门,其强度固定的费米子混合矩阵$V_{CKM}$和$V_{PMNS}$。这些模型是扩展到轻子部门的类模型先前考虑的布兰科,格里姆斯和Lavoura,夸克部门。我们认为这两种情况下的狄拉克和马约拉纳中微子,并确定所需的最小离散对称性,以实现在一个自然的方式模型。

英文摘要:

We construct extensions of the Standard Model with two Higgs doublets, where there are flavour changing neutral currents both in the quark and leptonic sectors, with their strength fixed by the fermion mixing matrices $V_{CKM}$ and $V_{PMNS}$. These models are an extension to the leptonic sector of the class of models previously considered by Branco, Grimus and Lavoura, for the quark sector. We consider both the cases of Dirac and Majorana neutrinos and identify the minimal discrete symmetry required in order to implement the models in a natural way.
