We present the first official release of the nCTEQ nuclear parton distribution functions with errors. The main addition to the previous nCTEQ PDFs is the introduction of PDF uncertainties based on the Hessian method. Another important addition is the inclusion of pion production data from RHIC that give us a handle on constraining the gluon PDF. This contribution summarizes our results from arXiv:1509.00792 and concentrates on the comparison with other groups providing nuclear parton distributions.

Detecting and studying high-energy collider neutrinos with FASER at the LHC (2019, background): “Although these effects can in principle be taken into account by using nuclear parton distribution functions [77–79], we note that they only lead to small (few %) changes in the cross section, and we therefore do not include then in this analysis [80].”
New observables in inclusive production of quarkonia (2019, methodology): “Since the EMC measurement [166], we know that the parton flux inside nuclei –as encoded in nuclear PDF (nPDF)[167, 168, 169, 170, 171, 172, 173]– differs from that of in the nucleon used as references.”
The Forward Physics Facility: Sites, experiments, and physics potential (2021, methodology): “Provided that these measurements are technically feasible and the integrated luminosity will be sufficient to accumulate enough statistics, in the simplest interpretation, such measurements would constrain nuclear PDFs in regions where they are currently even less constrained than proton PDFs, as sh”
Parton distributions and lattice-QCD calculations: Toward 3D structure (2020, background): “Other recent nuclear PDF sets, based on a more limited data set than EPPS16, are nCTEQ15 (Kovarik et al., 2016), TuJu19 (Walt et al., 2019), and nNNPDF1.”
