"Nucleon Form Factors from Lattice QCD"
ABSTRACT:
First-principles calculations of the nucleon form factors and generalized form factors have been made possible by employing the lattice QCD techniques. Together with the experimental efforts, lattice results for the nucleon form factors have deepened our understanding of the internal structure of the nucleon, such as the charge and current distributions, and the spin decomposition of the nucleon. In this talk, I will present some recent lattice QCD results for the nucleon form factors using a five-dimensional chirally symmetric fermion action. I will also address some challenges faced by modern lattice form factor calculations.
