最小行走人工色格子模拟中的近共形性探讨

Probes of nearly conformal behavior in lattice simulations of minimal walking technicolor

Simon Catterall, Joel Giedt, Francesco Sannino, Joe Schneible

摘要:

我们目前的结果,从高精度,大容量的模拟的格点规范理论对应的最小步行人工色。我们发现π介子衰变常数在无限体积极限下为零,手征凝聚体对夸克质量m_q的依赖性与自发对称性破缺不一致。这些发现与全阶β函数预测以及Schroedinger泛函研究一致,表明存在非平凡的红外不动点。

英文摘要:

We present results from high precision, large volume simulations of the lattice gauge theory corresponding to minimal walking technicolor. We find evidence that the pion decay constant vanishes in the infinite volume limit and that the dependence of the chiral condensate on quark mass m_q is inconsistent with spontaneous symmetry breaking. These findings are consistent with the all-orders beta function prediction as well as the Schroedinger functional studies that indicate the existence of a nontrivial infrared fixed point.
