摘要：

薛定谔泛函提供了一个有价值的工具来执行非微扰重整化的晶格，特别是在质量无关的计划。我们研究了两种不同类型的手性旋转Schroedinger泛函边界条件，最近提出了保持体自动O（a）的改进的无质量威尔逊费米子在有限体积。我们在连续谱中从微扰理论的树水平上研究了这两个方案的光谱性质和夸克传播子。

英文摘要：

The Schroedinger functional provides a valuable tool to perform non-perturbative renormalization on the lattice, in particular in a mass independent scheme. We study two different types of chirally rotated Schroedinger functional boundary conditions which have been recently proposed to retain the bulk automatic O(a) improvement of massless Wilson fermions in finite volume. We investigate the spectral properties and the quark propagators which derive from these two proposals in the continuum at tree-level of perturbation theory.

A perturbative study of the chirally rotated Schrödinger Functional in QCD

The chirally rotated Schrödinger functional ($χ$SF) renders the mechanism of automatic $O(a)$ improvement compatible with the Schrödinger functional (SF) formulation. Here we report on the determination to 1-loop order in perturbation theory of the renormalization coefficients necessary to achieve automatic $O(a)$ improvement and the boundary improvement coefficients needed to eliminate the extra boundary $O(a)$ effects present in any SF formulation. After this is done, we perform a set of tests of automatic $O(a)$ improvement and of the universality between standard and chirally rotated SF fo…

Perturbative renormalization of $ΔF = 2$ four-fermion operators with the chirally rotated Schrödinger functional

The chirally rotated Schrödinger functional ($χ$SF) renders the mechanism of automatic $O(a)$ improvement compatible with Schrödinger functional (SF) renormalization schemes. Here we define a family of renormalization schemes based on the $χ$SF for a complete basis of $ΔF = 2$ parity-odd four-fermion operators. We compute the corresponding scale-dependent renormalization constants to one-loop order in perturbation theory and obtain their NLO anomalous dimensions by matching to the $\overline{\textrm{MS}}$ scheme. Due to automatic $O(a)$ improvement, once the $χ$SF is renormalized and improved …

旋光边界条件下Schroedinger泛函的猝灭研究：应用

A quenched study of the Schroedinger functional with chirally rotated boundary conditions: applications

在文献[1]中，我们讨论了旋光薛定谔泛函（XSF）的非微扰调谐。需要进行这种调整以消除物理关联函数中的大量O（a）截止效应。利用我们在[1]中得到的调谐结果，我们进行标度和普适性测试，分析几个阶梯标度函数的剩余O（a）截止效应，并计算匹配标度下的重整化因子。作为一个可能的应用的XSF的例子，我们计算重整化的奇夸克质量使用大体积的数据从威尔逊扭曲的质量费米子在最大扭曲。

A dynamical study of the chirally rotated Schrödinger functional in QCD

The chirally rotated Schrödinger functional for Wilson-fermions allows for finite-volume, mass-independent renormalization schemes compatible with automatic O($a$) improvement. So far, in QCD, the set-up has only been studied in the quenched approximation. Here we present first results for $N_{\rm f} = 2$ dynamical quark-flavours for several renormalization factors of quark-bilinears. We discuss how these renormalization factors can be easily obtained from simple ratios of two-point functions, and show how automatic O($a$) improvement is at work. As a by-product of this investigation the renor…

旋光边界条件下的Schrodinger泛函

The Schrodinger functional with chirally rotated boundary conditions

使用orbifold技术，我构造了一个双合威尔逊夸克与手征旋转边界条件的薛定谔泛函（SF）。这允许执行普适性检查：例如，用任一边界条件定义的重整化SF耦合常数必须具有唯一的连续极限。类似地，扭曲质量QCD和标准QCD中的SF关联函数可以被定义为它们共享一个共同的连续极限。新的设置的一个额外的好处在于观察到，所有的散装O（a）counterterterms的行动和复合运营商成为无关的手征极限。这意味着SF重整化常数（比率）可以自动O（a）改进，直到不可避免的边界反项的影响。作为第一个应用程序，我们计算的运行耦合Nf=2的风味SF-计划的微扰理论的一个循环顺序。证明了连续极限的普适性，并明确地证明了作用量中Sheikholeslami-Wohlert项的无关性

具有Wilson费米子的手征旋转薛定谔泛函和自动O（a）改进

The chirally rotated Schrödinger functional with Wilson fermions and automatic O(a) improvement

提出了薛定谔泛函（SF）的一种修正形式。在连续谱中，它通过非单重手征场旋转与标准SF相关，因此被称为手征旋转SF（$χ$ SF）。在具有威尔逊费米子的晶格上，这种关系并不精确，这表明了一些有趣的普适性检验。$χ$ SF的主要优点在于它与自动O（$a$）改进机制的兼容性。本文介绍并讨论了基本设置。手征旋转SF边界条件的晶格上使用的orbifold建设。晶格的对称性意味着一系列的反项，这决定了如何的行动和基本的费米子两点函数重整化和O（$a$）的改进。与标准SF一样，一个几何发散的边界反项会导致费米边界场的乘法重整化。此外，为了保持相互作用理论中的旋光边界条件，必须调整有限维3边界反项。一旦实现了这一点，就可以通过自动O（$a$）改进的机制来避免源自批量操作或源自在批量中插入复合运算符的O（$a$）效应。剩余的O（$a$）效应产生于边界，并且可以通过调整一对O（$a$）边界反项来消除。的一般结果示出在自由理论中的Sheikholeslami-Wohlert长期被证明只在O（$a^2$）的关联函数的影响，无论其系数。

Nonperturbative running of the quark mass for $N_f=3$ QCD from the chirally rotated Schrödinger Functional

We study the Renormalisation Group (RG) running of the quark mass, for $N_f=3$ QCD with Wilson fermions in a mixed action setup, with standard Schrödinger Functional (SF) boundary conditions for sea quarks and chirally rotated Schrödinger Functional ($χ$SF) boundary conditions for valence quarks. This necessitates the tuning of the boundary factor $z_f(g_0^2)$ of the $χ$SF valence action, in order to ensure that QCD symmetries are fully recovered in the continuum. The properties of this novel setup are monitored through the ratios $Z_S/Z_P$ and $Σ_S/Σ_P$ of the renormalisation parameters and s…

The chirally rotated Schrödinger functional: theoretical expectations and perturbative tests

The chirally rotated Schrödinger functional ($χ$SF) with massless Wilson-type fermions provides an alternative lattice regularization of the Schrödinger functional (SF), with different lattice symmetries and a common continuum limit expected from universality. The explicit breaking of flavour and parity symmetries needs to be repaired by tuning the bare fermion mass and the coefficient of a dimension 3 boundary counterterm. Once this is achieved one expects the mechanism of automatic O($a$) improvement to be operational in the $χ$SF, in contrast to the standard formulation of the SF. This is e…

$χ$SF near the electroweak scale

We employ the chirally rotated Schrödinger functional ($χ$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 Schrödinger Functional (SF) boundary conditions. Valence quarks are computed with $χ$SF boundary conditions. We show preliminary results on the tuning of the $χ$SF Symanzik coefficient $z_f$ and the scaling of the axial current normalization $Z_{\rm A}$. Moreover we…
