论文摘要
我们研究了彩色Zee-Babu模型中的中微子双β衰变。我们考虑了带有Leptoquark的彩色Zee-Babu模型的三种情况，并引入了diquark。中微子的质量是在双环水平上产生的，并且已经考虑了树立型风味的过程和MUON异常磁矩$（G-2）_ $给出的约束。在我们的数值分析中，我们发现在某些假设和条件下，新的物理贡献可以取消标准的光中微子交换贡献，从而导致隐藏的中微子双重β衰减。可以通过不同的同位素进行未来的互补搜索来全面研究该条件。
We study the neutrinoless double beta decay in the colored Zee-Babu model. We consider three cases of the colored Zee-Babu model with a leptoquark and a diquark introduced. The neutrino masses are generated at two-loop level, and the constraints given by tree-level flavor violation processes and muon anomalous magnetic moment $(g-2)_μ$ have been considered. In our numerical analysis, we find that the standard light neutrino exchange contribution can be canceled by new physics contribution under certain assumption and condition, leading to a hidden neutrinoless double beta decay. The condition can be examined comprehensively by future complementary searches with different isotopes.
