Vector and axial nucleon form factors: A duality constrained parameterization
Vector and axial nucleon form factors: A duality constrained parameterization
We present new parameterizations of vector and axial nucleon form factors. We maintain an excellent descriptions of the form factors at low momentum transfers, where the spatial structure of the nucleon is important, and use the Nachtman scaling variable xi to relate elastic and inelastic form factors and impose quark-hadron …
