      N and N to Δ transition form factors from lattice QCD 

      Alexandrou, Constantia (2007)
      We present recent lattice QCD results on nucleon form factors and N to Δ transition form factors. We predict the parity violating asymmetry in N to Δ and check the off-diagonal Goldberger-Treiman relation.
