Uncertainties in the $\Delta$G Extraction from a Global Analysis of Polarized Data

ORAL

Abstract

In the latest global analysis from DSSV the $\Delta$G and its uncertainty are extracted based on polarized DIS and p+p collisions. Presently in the DSSV analysis the experimental uncertainties are all treated as uncorrelated. One way to improve our knowledge of $\Delta$G is to get a more complete understanding of these uncertainties. We do this by expanding the analysis to include experimental correlated uncertainties (like polarization). The results from this work together with an overview of the global analysis from DSSV will be discussed.
