The overall physics goals of our lattice calculations of hadron structure at light quark masses are:

  • To quantitatively calculate the experimentally observable properties of the nucleon and other hadrons from first principles.
  • To obtain insight into how QCD actually works in producing the rich and complex structure of hadrons.

To accomplish these goals, a hybrid combination of chiral domain wall valence quarks and dynamical improved staggered sea quark configurations provided by the MILC collaboration is being used to calculate a broad range of physical observables, including moments of structure functions, form factors, generalized form factors, nucleon density-density correlation functions, nucleon electric and magnetic polarizability, hadron wave functions, the nucleon to Delta transition form factors, the pion form factor and pentaquark observables.
