- Abstract
- We present results for pion and nucleon form factors, as well as the hadronic vacuum polari- sation contribution to the muon ( g 2) obtained from lattice QCD. By using O( a ) improved Wilson quarks for near-physical pion masses and three values of the lattice spacing we achieve good control over systematic errors associated with lattice artefacts and extrapolations to the physical pion mass. Several technical improvements are discussed, including the efficient cal- culation of quark-disconnected diagrams, the reduction of unwanted excited-state contributions in baryonic correlation functions, and the impact of using partially twisted boundary conditions
