Abstract

We employ the chirally rotated Schrodinger functional ($\chi$SF) to study two-point fermion bilinear correlation functions used in the determination of $Z_{A,V,S,P,T}$ on a series of well-tuned ensembles. The gauge configurations, which span renormalisation scales from 4 to 70~GeV, are generated with $N_{\rm f}=3$ massless flavors and Schrodinger Functional (SF) boundary conditions. Valence quarks are computed with $\chi$SF boundary conditions. We show preliminary results on the tuning of the $\chi$SF Symanzik coefficient $z_f$ and the scaling of the axial current normalization $Z_{\rm A}$. Moreover we carry out a detailed comparison with the expectations from one-loop perturbation theory. Finally we outline how automatically $\mathrm{O}(a)$-improved $B_{\rm K}$ matrix elements, including BSM contributions, can be computed in a $\chi$SF renormalization scheme.

$\chi$SF接近电弱尺度
利用手性旋转薛定谔泛函($\chi$SF)研究了用于确定一系列调谐系综上$Z_{A,V,S,P,T}$的两点费米子双线性相关函数。在$N_{\rm f}=3$无质量口味和薛定谔泛函(SF)边界条件下,生成了从4到70~GeV的重整化尺度的规范构型。用$\chi$SF边界条件计算价夸克。我们展示了$\chi$SF赛门铁克系数$z_f$的调谐和轴向电流归一化$Z_{\rm A}$的缩放的初步结果。并与单环摄动理论的期望进行了详细的比较。最后,我们概述了如何在$\chi$SF重整化方案中自动计算$\ mathm {O}(a)$改进的$B_{\rm K}$矩阵元素,包括BSM贡献。
