Light-cone algebra, field-current identity, and deep-inelastic scattering

The authors reproduce the full content of the Fritzsch-Gell-Mann light-cone algebra (originally derived using the quark model) for deep-inelastic lepton-nucleon scattering using currents given by the field-current identity. These currents are modified by dilaton clothing from the usual low-energy vector-dominance form by the principles of scale invariance to possess a scale dimension three (which is the dimension of the currents in the quark model). The calculation is performed by the technique of an effective Lagrangian to be used to first nonvanishing order, and the forms of the interactions needed to maintain the light-cone algebra are determined. The usual quark-parton results are explicitly obtained
