Parton Distribution Benchmarking with LHC Data

Ball, Richard D., Carrazza, Stefano, Del Debbio, Luigi et al.

Understand

We present a detailed comparison of the most recent sets of NNLO PDFs from the ABM, CT, HERAPDF, MSTW and NNPDF collaborations.

  • We compare parton distributions at low and high scales and parton luminosities relevant for LHC phenomenology.
  • We study the PDF dependence of LHC benchmark inclusive cross sections and differential distributions for electroweak boson and jet production in the cases in which the experimental covariance matrix is available.
  • We quantify the agreement between data and theory by computing the chi2 for each data set with all the various PDFs.
