QCD Analysis of the Polarized World Data
Johannes Blümlein, Helmut Böttcher
The results of a recent next-to-leading order QCD analysis of the world data on polarized deep inelastic scattering are reported. New parameterizations are derived for the quark an…
QCD Analysis of Polarized Deep Inelastic Scattering Data
Johannes Blümlein, Helmut Böttcher
A QCD analysis of the world data on polarized deep inelastic scattering is presented in next--to--leading order, including the heavy flavor Wilson coefficient in leading order in t…
Non--Singlet QCD Analysis of Deep Inelastic World Data at \boldmath
Johannes Blümlein, Helmut Böttcher, Alberto Guffanti
A non--singlet QCD analysis of the structure function in LO, NLO, NNLO and NLO is performed based on the world data for charged lepton scattering. We determine the…
NNLO analysis of unpolarized DIS structure functions
J. Blümlein, H. Böttcher, A. Guffanti
We present the results of a NNLO QCD analysis of the World data on unpolarized DIS Non-Singlet Structure functions.
Polarized Parton Densities
J. Blümlein, H. Böttcher
In this talk we summarize main results of a recent determination of the polarized deeply inelastic parton distributions to NLO from the world data. In the analysis the LO and NLO p…
Questions on Uncertainties in Parton Distributions
R. S. Thorne, H. Boettcher, A. M. Cooper-Sarkar +5
A discussion is presented of the manner in which uncertainties in parton distributions and related quantities are determined. One of the central problems is the criteria used to ju…
