摘要:

本文介绍了在格点量子色动力学计算中用2+1方法研究首级强子对μ子反常磁矩的贡献的有限体积效应的初步结果。我们还提出了直接获得不变的强子极化函数,$Π(Q^2)$,并在所有离散格点的$Q^2$,包括$Q^2=0$的Adler函数的方法。结果得到与HEX涂抹三叶草费米子。

英文摘要:

We present preliminary results of a 2+1-flavor study of finite-volume effects in the lattice QCD computation of the leading-order hadronic contribution to the muon anomalous magnetic moment. We also present methods for obtaining directly the invariant hadronic polarization function, $Π(Q^2)$, and the Adler function at all discrete lattice values of $Q^2$, including $Q^2=0$. Results are obtained with HEX-smeared clover fermions.
