ABSTRACT

Threshold photo- and electroproduction of neutral pions off nucleons are analysed in terms of the higher equal-time commutator 〈N|[∂νAν,Ve.m.|N〉, evaluated in the (\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$3,\bar 3$$ \end{document})⊕(\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document} $$\bar 3,3$$ \end{document}) model of Gell-Mann, Oakes and Renner. We discuss in particular the role of the chiral-symmetry-breaking parameters. Comparison with other, independent approaches leads to a size of the « proton-quark » mass consistent with the notion of approximateSU2×SU2 symmetry of hadrons. More... »
