SU的红外不动点(2)六味规范理论

Infrared fixed point of SU(2) gauge theory with six flavors

Viljami Leino, Kari Rummukainen, Joni M. Suorsa, Kimmo Tuominen, Sara Tähtinen

摘要:

我们计算了SU(2)规范理论中六个费米子在规范群基本表象中的耦合运行。建立了一个强耦合下的红外稳定不动点,并在该不动点上测量了费米子质量算符的反常维数。因此,这个理论很可能接近共形窗口的边界,如果与标准模型的电弱扇区相结合,将显示新的红外动力学。

英文摘要:

We compute the running of the coupling in SU(2) gauge theory with six fermions in fundamental representation of the gauge group. We establish an infrared stable fixed point at strong coupling and measure also the anomalous dimension of the fermion mass operator at the fixed point. This theory therefore likely lies close to the boundary of the conformal window and will display novel infrared dynamics if coupled with the electroweak sector of the Standard Model.
