Description
We present results for the vector and axial form factors of the isovector nucleon in $2+1$ flavour lattice QCD with Domain Wall fermions. Our pion mass is physical and the lattice spacing is $a=0.114$ fm. We extract the Dirac and Pauli form factors as well as the axial and induced pseudoscalar form factors, and study their momentum transfer dependence over the range $0.05 \lesssim Q^2 \lesssim 0.45\, \text{GeV}^2$. Additionally, we present results for the axial charge $g_A$, and electromagnetic and axial radii. We also discuss implications of the Partially Conserved Axial Current relation in the extraction of the axial form factor.
