TL;DR
This paper explores how incorporating new LHC data sets into the MMHT parton distribution functions improves uncertainties and discusses specific issues with ATLAS jet data and the effects of NNLO corrections.
Contribution
It introduces a method for including new LHC data into MMHT PDFs, addressing correlated uncertainties and NNLO effects, leading to improved PDF determinations.
Findings
Improved PDF uncertainties with new LHC data
Identified issues with ATLAS 7 TeV jet data
Preliminary results with ATLAS W,Z rapidity data
Abstract
I consider the effects of including a variety of new LHC data sets into the MMHT approach for PDF determination. I consider the impact of fitting new LHC and Tevatron data, which leads to clear improvements in some PDF uncertainties. There are specific issues with ATLAS 7 TeV jet data and I include a discussion of the treatment of correlated uncertainties and briefly the effects of NNLO corrections. I also present preliminary results with the inclusion of the high precison final ATLAS 7 TeV rapidity-dependent data.
