| Abstract: | A renormalization scheme invariant analysis of the deep inelastic scattering structure functionF 2 andF L is performed. Expressions for the moments are given in this approach. We find a significant improvement of the agreement withR=σ L /σ T -SLAC data with respect to the conventional perturvative \((\overline {MS} )\) analysis. Higher twist corrections are also required confirming previous evidence. |
