The Nucleon's e-N Axial Form Factor GAe 

Z0 has axial, as well as vector couplings  ® we measure axial FF too

GAZ:  neutral weak axial form factor, determined from neutron b decay and neutrino scattering

FA:  nucleon’s anapole moment – parity-violating electromagnetic moment

Re:  electroweak radiative corrections to e-N scattering
