Form factors from lattice QCD

Precision computation of hadronic physics with lattice QCD is becoming feasible.The last decade has seen percent-level calculations of many simple properties of mesons, and the last few years have seen calculations of baryon masses, including the nucleon mass, accurate to a few percent.As computational power increases and algorithms advance, the precise calculation of a variety of more demanding hadronic properties will become realistic.With this in mind, I discuss the current lattice QCD calculations of generalized parton distributions with an emphasis on the prospects for well-controlled calculations for these observables as well.I will do this by way of several examples: the pion and nucleon form factors and moments of the nucleon parton and generalizedparton distributions.
