双色Yang-Mills理论共形窗范围的格点研究

Lattice Study of the Extent of the Conformal Window in Two-Color Yang-Mills Theory

Gennady Voronov

摘要:

我们在SU(2)Yang-Mills理论中对六个无质量Wilson费米子的薛定谔泛函运行耦合进行了格点计算。本文的目的是确定上述理论是否存在红外不动点。由于$SF$重整化耦合对费米子裸质量调谐的敏感性,我们无法可靠地提取更强裸耦合的运行耦合。

英文摘要:

We perform a lattice calculation of the Schrödinger functional running coupling in SU(2) Yang-Mills theory with six massless Wilson fermions in the fundamental representation. The aim of this work is to determine whether the above theory has an infrared fixed point. Due to sensitivity of the $SF$ renormalized coupling to the tuning of the fermion bare mass we were unable to reliably extract the running coupling for stronger bare couplings.
