WebOct 1, 1993 · OSTI.GOV. Journal Article: Current algebras and the heavy quark limitCurrent algebras and the heavy quark limit Webculties stem from the failure to distinguish between two separate “quark models”. 2 In one model, dubbed the l’current quark” model by Gell-Mann, operators with the algebra of SUGw are defined as integrals of certain vector and tensor densities formed from local quark fields. 3 The SU2 x SU2 subalgebra Webmay really hold has motivated an extension of the hypotheses of current algebra to what may be called light–cone current algebra.1 As before, one starts from a field theoretical quark model (say one with neutral vector “gluons”) and abstracts exact algebraic results, postulating their validity for the real world of hadrons. raw frozen anchovies

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 … WebIn current algebra theory, results of approximate-symmetry models can be reproduced in two situations. ...
