The paper
Abstract
In this contribution we briefly report on the progress and open problems in parton distribution functions (PDFs), with emphasis on their implications for LHC phenomenology. Then we study the impact of the recent ATLAS and CMS W lepton asymmetry data on the NNPDF2.1 parton distributions. We show that these data provide the first constrains on PDFs from LHC measurements.
The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. No sentence in this record was written by a model.

We now turn to discuss the first constraints on PDFs from LHC data, provided by the ATLAS [ref] and CMS [ref] measurements of the leptonic $W$ asymmetry[There exist as well preliminary data from LHCb that will be sensitive to even smaller and larger values of $x$, see Fig. [ref].].
