Nucleon structure from mixed action calculations using2+1flavors of asqtad sea and domain wall valence fermions

Abstract

We present high statistics results for the structure of the nucleon from a mixed-action calculation using $2+1$ flavors of asqtad sea and domain-wall valence fermions. We perform extrapolations of our data based on different chiral effective field theory schemes and compare our results with available information from phenomenology. We discuss vector and axial form factors of the nucleon, moments of generalized parton distributions, including moments of forward parton distributions, and implications for the decomposition of the nucleon spin.
