摘要：In order to advance lattice calculations of moments of unpolarized, helicity, and transversity distributions,
electromagnetic form factors, and generalized form factors of the nucleon to a new
level of precision, this work investigates several key aspects of precision lattice calculations. We
calculate the number of configurations required for constant statistical errors as a function of pion
mass, describe the coherent sink method to help achieve these statistics, examine the statistical
correlations between separate measurements, study correlations in the behavior of form factors
at different momentum transfer, examine volume dependence, and compare mixed action results
with those using comparable dynamical domain wall configurations. We also show selected form
factor results and comment on the QCD evolution of our calculations of the flavor non-singlet
nucleon angular momentum.
