M. Fiohais et al., NUCLEON FORM-FACTORS IN A PROJECTED CHIRAL SOLITON MODEL WITH DYNAMICAL CONFINEMENT, Nuclear physics. A, 570(3-4), 1994, pp. 782-796
We calculate nucleon form factors in the framework of a chiral chromod
ielectric model. The model state describing the nucleon is an angular
momentum and isospin eigenstate with J = T = 1/2 obtained by means of
Peierls-Yoccoz projection from the hedgehog. We present results for th
e electromagnetic form factors and also for the axial form factors of
the nucleon. There is a fairly good agreement with the data for small
momentum transfers. For high momentum transfers (i.e. q2 > 0.1 GeV2) t
he agreement becomes poorer. As a general rule the calculated form fac
tors fall too rapidly.
