The nucleon spin structure in a simple quark model

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We investigate the spin structure of the nucleon in an extended Jaffe-Lipkin quark model. In addition to the conventional 3q3q structure, different (3q)(QQˉ)(3q)(Q\bar{Q}) admixtures in the nucleon wavefunction are also taken into account. The contributions to the nucleon spin from various components of the nucleon wavefunction are discussed. The effect due to the Melosh-Wigner rotation is also studied.
