惰性Zee模型中的带电轻子味破坏和电偶极矩

Charged lepton flavor violation and electric dipole moments in the inert Zee model

Alexandra Gaviria, Robinson Longas, Óscar Zapata

摘要:

惰性Zee模型是Zee中微子质量模型的扩展,它可以用来解决暗物质问题,暗物质问题涉及两个矢量场,一个是$SU(2)_L$的双重态和一个单重态,两个标量场,也是$SU(2)_L$的双重态和一个单重态,它们在精确的$Z_2$对称下都是奇数。$Z_2$的引入保证了单圈中微子质量,禁止了树级希格斯介导的味道改变中性电流,并确保了暗物质候选者的稳定性。由于惰性Zee模型中轻子数的自然破缺,以及寻找带电轻子味破坏信号和电子电偶极矩的雄心勃勃的实验计划的鼓励,我们研究了导致这类信号的过程的唯象,并确定了哪些是最有希望的实验观点。

英文摘要:

The inert Zee model is an extension of the Zee model for neutrino masses to allow for a solution to the dark matter problem that involves two vector-like fields, a doublet and a singlet of $SU(2)_L$, and two scalars, also a doublet and a singlet of $SU(2)_L$, all of them being odd under an exact $Z_2$ symmetry. The introduction of the $Z_2$ guarantees one-loop neutrino masses, forbids tree-level Higgs-mediated flavor changing neutral currents and ensures the stability of the dark matter candidate. Due to the natural breaking of lepton numbers in the inert Zee model and encouraged by the ambitious experimental program designed to look for charged lepton flavor violation signals and the electron electric dipole moment, we study the phenomenology of the processes leading to these kind of signals, and establish which are the most promising experimental perspectives on that matter.
