Abstract :
We present calculations of structure functions using a renormalization scheme consistent expansion which is leading order in both ln(1x) and αs(Q2). There is no factorization scheme dependence, and the “physical anomalous dimensions” of Catani naturally appear. A relationship between the small x forms of the inputs F2(x, Q02) and FL(x, Q02) is predicted. Analysis of a very wide range of data for F2(x, Q2) is performed, and a very good global fit obtained. The prediction for FL(x, Q2) produced using this method is smaller than the usual NLO in αs(Q2) predictions for FL(x, Q2), and different in shape.
