Lattice QCD calculation of the ${\pi }^0$-pole contribution to the hadronic light-by-light scattering in the anomalous magnetic moment of the muon

Tian Lin, Mattia Bruno, Xu Feng +4

We develop a method to compute the pion transition form factor directly at arbitrary space-like photon momenta and use it to determine the ${\pi }^0$-pole contribution to the hadronic l…
