摘要:
我们展示了由扩展扭质量协作组对在等旋对称QCD中muon异常磁矩的主导阶真空极化贡献的确定的最新进展。该计算基于五个N_f=2+1+1规范集合,这些集合使用Wilson-克利弗扭质量夸克在最大扭和近物理π质量下生成,覆盖了四个格子间距和两个体积。对于主导夸克连接贡献,我们采用两种不同的价夸克正则化方法,并给出了矢量和标量成分的结果。
英文摘要:
We present an update on the determination of the leading-order hadronic vacuum polarisation contribution to the muon anomalous magnetic moment in isospin-symmetric QCD by the Extended Twisted Mass Collaboration. The calculation is based on five $N_f = 2+1+1$ gauge ensembles generated with Wilson-clover twisted-mass quarks at maximal-twist and near-physical pion masses, spanning four lattice spacings and two volumes. For the dominant quark-connected contributions, we employ two distinct valence-quark regularisations and present results for both the isovector and isoscalar components.
