论文摘要
我们提供$ \ bar {\ mathrm {ms}} $ singlet轴向电流运算符在$ \ mathcal {o}（α_S^5）$扰动量子量子动力学（QCD）中的轴向轴流操作员的重新归化常数。该结果是从使用Adler-Bell-Jackiw方程得出的，就重新归一化的操作员而言获得的公式。所需的输入包括完整的四环结果，用于通过先前出版物中的显式示意性计算获得的操作员重归其化常数。
We provide the $\bar{\mathrm{MS}}$ factor of the renormalization constant of the singlet axial-current operator in dimensional regularization at $\mathcal{O}(α_s^5)$ in perturbative Quantum Chromodynamics (QCD). The result is obtained from a formula derived using the Adler-Bell-Jackiw equation in terms of renormalized operators. The required input consists of the complete four-loop results for operator renormalization constants obtained by explicit diagrammatic computation in a previous publication.
