I型+III跷跷板中的轻子味破坏

Lepton flavor violation in type I + III seesaw

Jernej F. Kamenik, Miha Nemevsek

摘要:

在低尺度的I + III型跷跷板的存在下,轻子部门的味道违反的影响是预期的。它们出现在带电区是由于类费米子矢量弱三重态与手征二重态的混合,导致了树能级Z耦合的非普适性。我们调查的Yukawa耦合的混合负责的界限,并提出了两个最小的情况下,一个费米子三重态与一个单重态或两个费米子三重态的结果。这些过程的不同渠道被认为是他们目前和未来的潜力,以探测这些耦合进行了讨论。

英文摘要:

In the presence of a low scale seesaw of type I + III, flavor violating effects in the leptonic sector are expected. Their presence in the charged sector is due to the mixing of the fermionic vector-like weak triplets with the chiral doublets, which cause non-universality of the tree-level Z coupling. We investigate the bounds on the Yukawa couplings which are responsible for the mixing and present the results for two minimal cases, a fermionic triplet with a singlet or two fermionic triplets. Different channels for these processes are considered and their current and future potential to probe these couplings is discussed.
