论文摘要
HADRONIC真空极化对MUON异常磁矩的贡献的“中间窗口量”允许数据驱动的方法与晶格QCD进行高精度比较。现有的晶格结果目前在彼此之间表现出良好的一致性，与数据驱动的确定有很大的张力。为了检查晶格计算的系统误差的潜在常见源，这些误差均基于时间摩托明表示（TMR），我们使用Lorentz-Covariant坐标空间（CCS）表示进行计算。我们在$（m_π，m_k）$ plane，Continuum和infinite-voLume量极限的$（m_π，m_k）$ plane的参考点上对ISOVECTOR和连接的奇怪夸克贡献，基于四个不同的晶格间距。我们的结果与最近基于TMR的Mainz-CLS出版物的结果非常吻合。
The `intermediate window quantity' of the hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon allows for a high-precision comparison between the data-driven approach and lattice QCD. The existing lattice results, which presently show good consistency among each other, are in strong tension with the data-driven determination. In order to check for a potentially common source of systematic error of the lattice calculations, which are all based on the time-momentum representation (TMR), we perform a calculation using a Lorentz-covariant coordinate-space (CCS) representation. We present results for the isovector and the connected strange-quark contributions to the intermediate window quantity at a reference point in the $(m_π,m_K)$ plane, in the continuum and infinite-volume limit, based on four different lattice spacings. Our results are in good agreement with those of the recent TMR-based Mainz-CLS publication.
