WebAn alternative is proposed to specific Lagrangian models of current algebra. In this alternative there are no explicit canonical fields, and operator products at the same point [say, ${j}_{\\ensuremath{\\mu}}(x){j}_{\\ensuremath{\\mu}}(x)$] have no meaning. Instead, it is assumed that scale invariance is a broken symmetry of strong interactions, as … WebThe basic ideas for the subject of current algebra were introduced by Gell-Mann [1] as long ago as 1961. But the development proceeded slowly for several years, until 1965, when …
