Kusina, A.; Lyonnet, F.; Clark, D. B.; Godat, E.; Ježo, T.; Kovařík, K.; Olness, F. I.; Schienbein, I.; Yu, J. Y.

Here, we provide a comprehensive comparison of W^±/Z vector boson production data in pPb and PbPb collisions at the LHC with predictions obtained using the nCTEQ15 PDFs. We also identify the measurements which have the largest potential impact on the PDFs, and estimate the effect of including these data using a Bayesian reweighting method. We find this data set can provide information as regards both the nuclear corrections and the heavy flavor (strange quark) PDF components. As for the proton, the parton flavor determination/separation is dependent on nuclear corrections (from heavy target DIS, for example), this information can also help improve the proton PDFs.
