abstract = {Accessing hadronic form factors at large momentum transfers
has traditionally presented a challenge for lattice QCD
simulations. Here, we demonstrate how a novel implementation
of the Feynman-Hellmann method can be employed to calculate
hadronic form factors in lattice QCD at momenta much higher
than previously accessible. Our simulations are performed on
a single set of gauge configurations with three flavors of
degenerate mass quarks corresponding to mπ≈470 MeV.
We are able to determine the electromagnetic form factors of
the pion and nucleon up to approximately 6 GeV2, with
results for the ratio of the electric and magnetic form
factors of the proton at our simulated quark mass agreeing
well with experimental results.},
