$C_5^A$ form factor from ANL experiment

$C_5^A(Q^2)$ axial form factor is extracted from the ANL neutrino-deuteron scattering data with deuteron structure effects taken into consideration. The best fit of the $C_5^A(Q^2)$ axial form factor is obtained assuming dipole parametrization with $C_5^A(0)=1.13\pm 0.15$ and $M_A=0.94\pm 0.08$ GeV.
