论文摘要
我们向计算$π^0 $，$η$和$η^{\ prime} $过渡形式的进度报告，使用交错的夸克在$ n_f = 2+1+1+1 $ 1 $ gauge emembles上，由布达佩斯 - 梅拉斯·马勒斯·梅尔·韦珀特尔（Budapest-Mardele-Masseille-Wuppertal）协作产生。这些形式是评估伪尺度杆对MUON $ G-2 $中光线散射的伪cal-Pole贡献的必要成分。在有限的晶格间距上，为所有三个轻介子介绍了伪级极贡献的初步结果。
We report on our progress toward the computation of the $π^0$, $η$ and $η^{\prime}$ transition form factors using staggered quarks on $N_f=2+1+1$ gauge ensembles generated by the Budapest-Marseille-Wuppertal collaboration. These form factors are essential ingredients to evaluate the pseudoscalar-pole contributions to the hadronic light-by-light scattering in the muon $g-2$. Preliminary results for the pseudoscalar-pole contributions are presented, at finite lattice spacing, for all three light mesons.
