论文摘要
我们在SM的扩展中提出了一组最小的弱基础不变式，其中引入了一个Up-type Isosinglet矢量样Quark，这使我们能够获得CKM矩阵的所有物理内容。我们比SM中的CP-ODD不变质量不变，这可能对男性生成有重要影响。我们研究了极端的手性极限，其中两个最轻的世代的质量消失了，这表明，在此扩展中，与SM相反，可以在碰撞中观察到违反CP的行为。
We propose a minimal set of weak-basis invariants in an extension of the SM where one up-type isosinglet vector-like quark is introduced, which allows us to obtain all the physical content of the CKM matrix. We present CP-odd invariants of lower order in mass than the one in the SM, which may have important consequences for Baryogenesis. We study the extreme chiral limit, where the two lightest generations have vanishing mass, showing that in this extension, contrary to the SM, CP violation can be observed in collisions much above the electroweak scale.
