论文摘要
我们使用带有不同夸克质量和晶格间距的手性费米子在非扰动量表下调查了landau量规下的ri'/妈妈夸克质量的起源。 Our result confirms that such a mass is non-vanishing based on the linear extrapolation to the chiral and continuum limit, and shows that such a mass comes from the spontaneous chiral symmetry breaking induced by the near zero modes with the eigenvalue $λ<{\cal O}(5m_q)$, and is proportional to the quark matrix element of the trace anomaly at least down to $ \ sim $ 1.3 GEV。
We investigated the origin of the RI'/MOM quark mass under the Landau gauge at the non-perturbative scale, using the chiral fermion with different quark masses and lattice spacings. Our result confirms that such a mass is non-vanishing based on the linear extrapolation to the chiral and continuum limit, and shows that such a mass comes from the spontaneous chiral symmetry breaking induced by the near zero modes with the eigenvalue $λ<{\cal O}(5m_q)$, and is proportional to the quark matrix element of the trace anomaly at least down to $\sim $1.3 GeV.
