CKM幺正三角形的辐射修正

Radiative Corrections to the CKM Unitarity Triangles

Shu Luo, Zhi-zhong Xing

摘要:

3 X 3 CKM矩阵在复平面上定义了六个幺正三角形,这将在LHCb实验和Super-B工厂中仔细探索。利用单圈重整化群方程计算了从电弱尺度到超高能尺度的六个三角形的九个内角和十八条边的运行效应,证明了这九个内角和十八条边都是稳定的.特别地,我们发现CP破坏角α对能量标度的变化最不敏感.

英文摘要:

The 3 X 3 CKM matrix defines six unitarity triangles in the complex plane, which will be carefully explored in the LHCb experiment and at the Super-B factory. We calculate the running effects of nine different inner angles and eighteen different sides of the six triangles from the electroweak scale to a superhigh-energy scale by using the one-loop renormalization-group equations, and demonstrate that all the nine angles are stable against radiative corrections. In particular, we find that the CP-violating angle αis most insensitive to the changes of energy scales.
