Form factors from lattice QCD

Understand

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.
