Complete Renormalization Group Improvement- Avoiding Factorization and Renormalization Scale Dependence in QCD Predictions
نویسنده
چکیده
For moments of leptoproduction structure functions we show that all dependence on the renormalization and factorization scales disappears provided that all the ultraviolet logarithms involving the physical energy scale Q are completely resummed. The approach is closely related to Grunberg’s method of Effective Charges. A direct and simple method for extracting ΛMS from experimental data is advocated. ) [email protected] ) [email protected]

Complete Renormalization Group Improvement - Avoiding Scale Dependence in QCD Predictions
We show that dimensionful renormalization scheme parameters such as the renormalization or factorization scale can be completely eliminated from perturbative QCD predictions provided that all the ultraviolet logarithms involving the physical energy scale Q are completely resummed.
متن کاملDirect extraction of QCD ΛMS from moments of structure functions in neutrino-nucleon scattering, using the CORGI approach
We use recently calculated next-to-next-to-leading (NNLO) anomalous dimension coefficients for the n = 1, 3, 5, . . . , 13 moments of the xF3 structure function in νN scattering, together with the corresponding three-loop Wilson coefficients, to obtain improved QCD predictions for the moments. The Complete Renormalization Group Improvement (CORGI) approach is used, in which all dependence on re...

We use recently calculated next-to-next-to-leading order (NNLO) anomalous dimension coefficients for the moments of the xF3 structure function in νN scattering, together with the corresponding three-loop Wilson coefficients, to obtain improved QCD predictions for both odd and even moments. To investigate the issue of renormalisation scheme dependence the Complete Renormalization Group Improveme...
متن کاملComplete renormalization group improvement of QCD perturbation theory
We suggest that at any given order of Feynman diagram calculation for a QCD observable all renormalization group (RG)-predictable terms should be resummed to all-orders. This “complete” RG-improvement (CORGI) serves to separate the perturbation series into infinite subsets of terms which when summed are renormalization scheme (RS)-invariant. Crucially all ultraviolet logarithms involving the di...
متن کاملQCD Corrections to Associated tt̄h Production at the Tevatron
We present in detail the calculation of the O(α 3 s) inclusive total cross section for the process pp → tth in the Standard Model, at the Tevatron center-of-mass energy √ s H = 2 TeV. The next-to-leading order QCD corrections significantly reduce the renormalization and factorization scale dependence of the Born cross section. They slightly decrease or increase the Born cross section depending ...
