论文摘要
我们提出了一种机制，该机制将迪拉克中微子质量驱动到沿重新归一化的沿线流动，从渐近安全的紫外线完成，包括量子重力的第三代标准模型。同时，该机制在中微子和夸克部门之间产生质量分解，并在顶部和底部夸克之间产生质量分裂。该机制取决于费米子的超负荷，并产生一个微小的中微子Yukawa耦合，因为右手中微子是无菌的，并且不带有超收费。
We present a mechanism which drives Dirac neutrino masses to tiny values along the Renormalization Group flow, starting from an asymptotically safe ultraviolet completion of the third generation of the Standard Model including quantum gravity. At the same time, the mechanism produces a mass-splitting between the neutrino and the quark sector and also generates the mass splitting between top and bottom quark. The mechanism hinges on the hypercharges of the fermions and produces a tiny neutrino Yukawa coupling, because the right-handed neutrino is sterile and does not carry hypercharge.
