The qqq model of Mitra for meson-baryon processes is reformulated to study inclusive processes incorporating charm and color degrees of freedom. Predictions are made in terms of sum rules for various inclusive cross sections. Agreement of the sum rules with data is good for du/dpL2 and du/dx in the available range ofpl*/x. However, overall analysis of the flavor-symmetry breaking indicates that symmetries alone are not adequate and the underlying theory should contain a suitable mechanism to generate Regge-type behavior in the inclusive distributions. We also incorporate proton-wave-function modification due to gluons in our model.
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.
