摘要:

我们首次完整计算了Jarlskog不变量——这是衡量三种轻中微子味道振荡中CP破坏强度的有效度量,借助规范跷跷板机制中味道结构的完整类Euler块参数化。我们发现该不变量依赖于6个原始相位参数的240个线性组合,这些参数负责三个重Majorana中微子衰变中的CP破坏,整体以27个线性组合的形式呈现,从而首次提供了微观与宏观物质-反物质不对称性之间的模型无关联系。

英文摘要:

We present the first complete calculation of the Jarlskog invariant, a working measure of the strength of CP violation in the flavor oscillations of three light neutrino species, with the help of a full Euler-like block parametrization of the flavor structure in the canonical seesaw mechanism. We find that this invariant depends on 240 linear combinations of the 6 original phase parameters that are responsible for CP violation in the decays of three heavy Majorana neutrinos in 27 linear combinations as a whole, and thus provides the first model-independent connection between the microscopic and macroscopic matter-antimatter asymmetries.
