TL;DR
This paper outlines the development of a new comprehensive nCTEQ nuclear PDF analysis that integrates diverse datasets, including neutrino DIS, JLab high-x data, and LHC p-Pb data, to enhance understanding of nuclear parton distributions.
Contribution
It introduces a unified framework for nCTEQ nuclear PDFs incorporating recent data and theoretical updates, notably including neutrino DIS data in a consistent manner.
Findings
Improved description of strange quark PDFs at low-x.
Enhanced gluon PDF constraints from LHC p-Pb data.
First nCTEQ release with integrated neutrino DIS data.
Abstract
We discuss the foundation for a new global nCTEQ nuclear PDF analysis, combining a number of our previous analyses into one consistent framework with updates to the underlying theoretical treatment as well as the addition of new available data. In particular, the new global release will be the first nCTEQ release containing neutrino DIS scattering data in a consistent manner together with JLab high-x DIS data and new LHC p-Pb data. These additions will improve the data-driven description of nuclear PDFs in new regions, especially the strange quark and the gluon PDF at low-x.
