Semileptonic decays, magnetic moments and spin distributions of spin-1/2 baryons with sea contribution
V. Gupta, R. Huerta, G. Sanchez-Colon
Abstract
Spin-1/2 baryons are considered as a composite system made out of a "core" of three quarks surrounded by a "sea" (of gluons and qq-pairs) which is specified by its total quantum numbers. Specifically, we assume this sea to be a flavor octet with spin-0 or 1 but no color. We show our model can provide very goods fits to magnetic moments and semileptonic decay data using experimental errors. The predictions for spin distributions are in reasonable agreement with experiment.
