Towards the NNPDF3.0 parton set for the second LHC run

TL;DR

The paper introduces the NNPDF3.0 parton distribution functions, incorporating extensive new LHC and HERA data with improved fitting methods to enhance the precision of theoretical predictions at hadron colliders.

Contribution

It presents the development of the NNPDF3.0 PDF set, featuring an improved fitting methodology and inclusion of over a thousand new experimental data points.

Findings

Enhanced PDF uncertainties with new data inclusion

Validation of the fitting methodology through closure tests

Impact of LHC and HERA data on PDF precision

Abstract

The full exploitation of the increasingly precise LHC measurements is essential in order to reduce the uncertainty of theoretical predictions at hadron colliders. The NNPDF2.3 fit was the first PDF determination including the effect of the early LHC data. Here the new NNPDF3.0 PDF set is announced and its main features are presented. The novel NNPDF analysis is based on an improved fitting methodology, statistically validated by closure tests. Over a thousand new data points are included, both the recent HERA II measurements and a wide set of new LHC data. In this contribution details on the experimental data are given and their impact on PDF uncertainties is displayed.
