Description
We present preliminary results of a new global QCD analysis of PDFs
from the CTEQ-Jefferson Lab Collaboration (dubbed "CJ15"), which
includes several new data sets and recent theoretical developments.
In particular, we study the constraints from new D0 data on *W* boson
asymmetries on the *d/u* PDF ratio at large *x*, and, indirectly, on
the models of nuclear corrections in the deuteron. The analysis
also considers for the first time the impact of Jefferson Lab data
on the free neutron/deuteron structure function ratio at large *x*,
and reanalyzes the light antiquark asymmetry in the proton from
Drell-Yan data using more flexible parametrizations and nuclear
corrections to deuterium cross sections. The results provide a
new set of baseline PDFs which can be used to more reliably
calibrate the effect of future data from the LHC.
