Title: Toward NNLO accuracy of parton distribution functions

Dr. Pavel Nadolsky


I will review physics issues arising in the development of next-to-next-to-leading order (NNLO) parton distribution functions. A variety of factors affects the PDFs at the level comparable to NNLO QCD corrections. I will discuss recent efforts by PDF analysis groups aimed at understanding the interplay of such factors and developing PDF sets that will match the NNLO accuracy required from QCD predictions for key LHC processes.
