This talk will motivate three calculations being done by the Los Alamos lattice QCD team: (i) axial vector form factors of nucleons needed to reach the design goals of the DUNE neutrino oscillation experiment, (ii) the pion-nucleon sigma term, and (iii) the contributions from beyond the standard model physics to the neutron electric dipole moment. The talk will discuss a major systematic in these calculations—the contributions from multiparticle excited states that the LANL team has pioneered methods to identify and remove. Current state of results on these observables from lattice QCD will be presented.
