Abstract

The LHC heavy ion data for W/Z production can provide new incisive
information on the PDFs. This data is sensitive to the heavier quark
flavors (strange and charm) in a high energy kinematic region; this
can facilitate the determination of PDFs in the small x region where
previous data was limited. At present, the flavor separation of the
proton PDFs is dependent on DIS data from nuclear targets. Therefore,
improved nuclear corrections can also yield enhanced flavor
determination of both the proton and nuclear PDFs.
