论文摘要
我们研究了标量发条模型中生成正确风味中微子质量基质的能力。首先，我们假设风味结构由Yukawa耦合控制与标准模型相同。在这种情况下，可以通过适当的Yukawa耦合$ y _ _ {\ Ell^\ prime \ ell} $获得正确的风味中微子质量矩阵，其中$ \ ell^\ prime，\ ell = e = e，μ，τ$。接下来，我们假设Yukawa耦合是极端民主的$ | y _ {\ ell^\ prime \ ell} | = 1 $。在这种情况下，标量发条扇区的模型参数（例如发条链中发条齿轮的站点编号）应具有风味指数$ \ ell^\ prime $和/或$ \ ell $，以生成正确的风味中微子质量质量矩阵。我们展示了一些风味指数分配的例子，这些示例可以产生正确的风味中微子质量基质。
We study the capability of generating correct flavor neutrino mass matrix in a scalar clockwork model. First, we assume that the flavor structure is controlled by the Yukawa couplings as same as the standard model. In this case, the correct flavor neutrino mass matrix could be obtained by appropriate Yukawa couplings $Y_{\ell^\prime\ell}$ where $\ell^\prime, \ell = e, μ, τ$. Next, we assume that the Yukawa couplings are extremely democratic $|Y_{\ell^\prime\ell} |=1$. In this case, the model parameters of the scalar clockwork sector, such as the site number of a clockwork gear in a clockwork chain, should have the flavor indices $\ell^\prime$ and/or $\ell$ to generate correct flavor neutrino mass matrix. We show some examples of the assignments of the flavor indices which can yield the correct flavor neutrino mass matrix.
