论文摘要
我们提出了这样一个猜想，即$ v_ \ text {ckm} $矩阵中的小数字是由标准模型以外的物理生成的。我们将其标识为小数字$ v_ {ub} $和CP违规的强度，由$ | \ text {im} q | $衡量，其中$ q $代表$ v_ \ text {ckm} $的不变四重奏。我们说明了如何在标准模型的扩展的上下文中实现猜想，其中引入了类似于上的矢量的夸克，从而导致了与实验达成一致的有效$ v_ \ text {ckm} $的现实频谱。
We put forward the conjecture that the small numbers in the $V_\text{CKM}$ matrix, are generated by physics beyond the Standard Model. We identify as small numbers $V_{ub}$ and the strength of CP violation, measured by $|\text{Im}Q|$, where $Q$ stands for a rephasing invariant quartet of $V_\text{CKM}$. We illustrate how the conjecture can be realised in the context of an extension of the Standard Model where an up-type vector-like quark is introduced leading to a realistic spectrum of quark masses and an effective $V_\text{CKM}$ in agreement with experiment.
