Description
Nuclear parton distribution functions (nPDFs) are a key ingredient for precision studies of high-energy nuclear collisions. This talk will review the current status of global nPDF analyses, focusing on recent determinations including EPPS21, nNNPDF3.0, and nCTEQ26. We will discuss the impact of new experimental constraints, similarities and differences between the various fitting frameworks, and the resulting uncertainties on parton distributions in nuclei. Special attention will be paid to the strange-quark and gluon distributions, as well as to the nuclear (A) dependence.
