Abstract
We present results on the nucleon axial vector form factors GA(q) and Gp(q) in the quenched theory and using two degenerate flavors of dynamical Wilson fermions for momentum transfer squared from about 0.1 to about 2 GeV2 and for pion masses in the range of 380 to 600 MeV. We also present results on the corresponding N to ∆ axial vector transition form factors CA 5 (q 2) and CA 6 (q 2) using, in addition to Wilson fermions, domain wall valence quarks and dynamical staggered sea quarks provided by the MILC collaboration.
