无异常模型中的Sumino消去机制

Sumino's Cancellation Mechanism in an Anomaly-Free Model

Yoshio Koide

摘要:

Sumino提出了一个有趣的族规范玻色子(FGB)模型(Model A)。模型A的一个基本思想是在QED图和FGB图之间引入了Sumino消去机制,它可以给出能量标度相当低的FGB图,而不受观测到的$K^0$ - $\bar{K}^0$混合等约束。然而,模型A不是无异常的,此外,它引起与$ΔN_{\rm family}=2$的有效交互。为了避免这些问题,人们提出了一个修正的Sumino模型(模型B),但是,在这个时候,它不能完全满足Sumino取消机制。在本文中,我们提出了一个修改版本的模型B,该模型仍然保持异常自由,但它可以完全满足Sumino机制。将通过观察结果$K^+ \rightarrow π^+ e^- μ^+$和$μ^- N\rightarrow e^- N$确认修订模型的影响。

英文摘要:

An interesting family gauge boson (FGB) model (Model A) has been proposed by Sumino. The model can give FGBs with a considerably low energy scale in spite of the sever constraints form the observed $K^0$-$\bar{K}^0$ mixing and so on. An essential idea in Model A is in the so-called Sumino cancellation mechanism between QED and FGB diagrams. However, Model A is not anomaly free and, besides, it causes effective interactions with $ΔN_{\rm family}=2$. In order to avoid these problems, a revised Sumino model with an inverted mass hierarchy (Model B) has proposed, but, in this time, it cannot satisfy the Sumino cancellation mechanism exactly. In this paper, we propose a revised version of Model B, where the model still keeps anomaly free, but it can exactly satisfy the Sumino mechanism. An effect of the revised model will be confirmed by observations $K^+ \rightarrow π^+ e^- μ^+$ and $μ^- N\rightarrow e^- N$.
