NNLO nuclear parton distribution functions with electroweak-boson production data from the LHC

Understand

We present new sets of nuclear parton distribution functions (nPDFs) at next-to-leading order and next-to-next-to-leading order in perturbative QCD.

• Our analyses are based on deeply inelastic scattering data with charged-lepton and neutrino beams on nuclear targets, and experimental data from measurements of $W^{\pm},\,Z$ boson production in p+Pb collisions at the LHC.
• In addition, a set of proton baseline PDFs is fitted within the same framework and with the same theoretical assumptions.
• The results of our global QCD analysis are compared to existing nPDF sets and to the previous nPDF set TUJU19 which was based on DIS data only.
