Insight Into

An extensive program of parity-violating electron scattering experiments is providing new insight into the structure of the nucleon. Measurement of the vector form factors enables a definitive study of potential strange quark-antiquark contributions to the nucleon's electromagnetic structure, including the magnetic moment and charge distribution. Recent experimental results have already indicated that effects of strangeness are much smaller than theoretically expected. In addition, the neutral axial form factor appears to display substantial corrections as one might expect from an anapole effect.

Moment Distribution

This article deals with the form factor of the anomalous magnetic moment distribution of proton and neutron. It is first shown with three examples that the magnetic root mean square radius cannot be taken from the existing experiments with sufficient accuracy. Satisfactory agreement with the experimental results can be obtained with arbitrary values of rm2. We calculate the magnetic moment form factors depending on the energy momentum transfer q2 in perturbation theory and the 2 π meson contribution to the isotopic vector form factor with dispersion relations also in relation to q2, with and without π meson form factor. We get better agreement of the shape of the form factor with the phenomenological form factor of HOFSTADTER at the expense of the static magnetic moment. But the contribution of the high q2 values is still too large i.e. the structure is somewhat too concentrated **
