This is the third part of a series of work that we have done in the context of the meson cloud model. In the first two parts [F. Zamani, Phys. Rev. C 58, 3641 (1998); F. Zamani and D. Saranchak, Phys. Rev. C 63, 065202 (2001)] we used pseudoscalar mesons to calculate unpolarized and polarized quark distribution functions along with the nucleon's F 2 and g 1 structure functions. Now we have added the vector mesons to the meson cloud to calculate the polarized quark distribution functions and g 1 structure function. The calculation is performed in the light-cone frame. The dressed nucleon is assumed to be a superposition of the bare nucleon plus virtual light-cone Fock states of baryon-meson pairs. For bare nucleon we consider both the case of diquark-quark clustering and the case where there is no quark clustering inside the nucleon. The initial distributions are evolved. The final results are compared with experimental results and other theoretical predictions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
