The PDF4LHC Working Group Interim Report
This document is intended as a study of benchmark cross sections at the
LHC (at 7 TeV) at NLO using modern parton distribution functions currently
available from the 6 PDF fitting groups that have participated in this
exercise. It also contains a succinct user guide to the computation of
PDFs, uncertainties and correlations using available PDF sets.
A companion note, also submitted to the archive, provides an interim
summary of the current recommendations of the PDF4LHC working group for
the use of parton distribution functions and of PDF uncertainties at the
LHC, for cross section and cross section uncertainty calculations.
