Description
Storing theoretical predictions for collider observables independent
from PDFs is a worthwhile goal from at least two different perspectives:
As a theorist producing the theoretical predictions this enables one to
quickly change the PDF set and thereby to assess possible differences of
the PDF sets. From the perspective of someone fitting a new PDF set, the
PDF-independent theoretical predictions are one neccessary ingredient of
the fitting procedure.
The problem described above is well-known and solved for QCD in the
public frameworks APPLgrid and fastNLO. Two points which are so far
unaddressed, however, are the treatment of electroweak corrections and
the inclusion of photon-induced contributions. They will become
important because the next generation of PDFs are about reach a level of
precision where the inclusion of next-to-leading order electroweak
effects becomes important.
In this talk I am going to describe the problem in more detail and the
status of our effort addressing it.
