摘要:

我们探讨了SU(2)和SU(3)格点规范理论在强耦合下的相位结构,在基本表象中,威尔逊费米子的许多味道$N_f$。至少对于足够大的$N_f$,观察到作为跳跃参数的函数的赝标介子质量偏离预期的解析依赖性。这种效果的影响进行了讨论,包括最近的搜索红外固定点的相关性。

英文摘要:

We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong coupling with many flavours $N_f$ of Wilson fermions in the fundamental representation. The pseudoscalar meson mass as a function of hopping parameter is observed to deviate from the expected analytic dependence, at least for sufficiently large $N_f$. Implications of this effect are discussed, including the relevance to recent searches for an infrared fixed point.
