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.
