Nucleon form factors and spin content in a quark-diquark model with a pion cloud
arXiv:1204.4422 · doi:10.1103/PhysRevC.86.015208
Abstract
We propose a new model of the nucleon in which quark-diquark configurations immersed in a pion cloud are treated in a manner consistent with Poincaré invariance. With suitably chosen parameters, the computations employing this model reproduce the measured electromagnetic form factors and the quark-spin contribution to the total nucleon angular momentum.
