Vacuum polarization in QED with an electromagnetic background from the lattice
En-Hung Chao
We propose a framework to determine the vacuum polarization functions in QED in the presence of an electromagnetic background field in the spacelike region on the lattice. This met…

Long-distance contributions to kaon decays on the lattice
En-Hung Chao
In the past decades, significant improvements have been made on standard-model predictions on kaon decays using lattice quantum chromodynamics. In these proceedings, I review selec…

Computing the UV-finite electromagnetic corrections to the hadronic vacuum polarization in the muon from lattice QCD
Julian Parrino, Volodymyr Biloshytskyi, En-Hung Chao +2
In order to reach a precision of on the hadronic vacuum polarization (HVP) contribution to the anomalous magnetic moment of the muon, , such that the full Standar…
