Description
Drell-Yan process plays an important role in the phenomenology of
the LHC era. This process is used extensively in parton distribution
function extractions. Predictions with high theoretical accuracy and
good numerical stability are key for high precision PDF extractions.
This process is calculated in the literature at the NNLO QCD accuracy
by multiple groups. So far no thorough comparison was done between
these calculations. In my talk I would like to present the first such
comparison of available computer programs with an emphasis on the differences
found in numerical results with discussion on their possible sources.
