Description
We report a recent breakthrough in lattice QCD calculations of hadron
form factors at large momentum transfer. Conventional lattice
form-factor calculations typically reach about 2.5 GeV$^2$ or less,
but in this work the transfer momentum is pushed as high as 6 GeV$^2$.
Our approach can be applied to isotropic lattices and lattices with
smaller lattice spacing to calculate even larger-$Q2$ form factors.
We will discuss the methodology and demonstrate results for the
nucleon and pion from 2+1-flavor anisotropic clover lattices.
These measurements could give important theoretical input to
experiments, such as those of JLab's 12-GeV program, and provide
insight into hadronic structure.
