RAL-96-088 Renormalization Scheme Consistent Structure Functions, Including Leading ln(1/x) Terms.
نویسنده
چکیده
We present calculations of structure functions using a renormalization scheme consistent expansion which is leading order in both ln(1/x) and αs(Q ). 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,Q 2 0) and FL(x,Q 2 0) is predicted. Analysis of a very wide range of data for F2(x,Q ) is performed, and a very good global fit obtained. The prediction for FL(x,Q ) produced using this method is smaller than the usual NLO in αs(Q ) predictions for FL(x,Q ), and different in shape. RAL-96-088 October 1996

متن کاملA Complete Leading–order, Renormalization–scheme–consistent Calculation of Small–x Structure Functions, including Leading–ln(1/x) Terms
We present calculations of the structure functions F2(x,Q ) and FL(x,Q ), concentrating on small x. After discussing the standard expansion of the structure functions in powers of αs(Q ) we consider a leading–order expansion in ln(1/x) and finally an expansion which is leading order in both ln(1/x) and αs(Q ), and which we argue is the only really correct expansion scheme. Ordering the calculat...
متن کاملA Complete Leading–order Renormalization–scheme–consistent Calculation of Structure Functions
We present consistently ordered calculations of the structure functions F2(x,Q ) and FL(x,Q ), in different expansion schemes. After discussing the standard expansion in powers of αs(Q ) we consider a leading–order expansion in ln(1/x) and finally an expansion which is leading order in both ln(1/x) and αs(Q ), and which is the only really correct expansion scheme. Ordering the calculation in a ...
متن کاملNext-to-Next-to-Leading Logarithmic Threshold Resummation for Deep-Inelastic Scattering and the Drell-Yan Process
The soft-gluon resummation exponents G in moment space are investigated for the quark coefficient functions in deep-inelastic structure functions and the quark-antiquark contribution to the Drell-Yan cross section dσ/dM . Employing results from twoand three-loop calculations we obtain the next-to-next-to-leading logarithmic terms αs(αs lnN) n of G to all orders in the strong coupling constant α...
متن کاملA Leading–Order, But More Than One–Loop, Calculation of Structure Functions
I present a full leading–order calculation of F2(x,Q ) and FL(x,Q ), including contributions not only from leading order in αs, but also from the leading power of αs for each order in ln(1/x). The calculation is ordered according to the inputs and evolution of the structure functions, and the perturbative form of the inputs is determined. I compare the results of fits to data to those using con...
