Query: The LHC p+Pb run from the nuclear PDF perspective   The p+Pb and Pb+Pb runs at the LHC have opened a possibility to investigate
the validity of collinear factorization in a clearly higher center-of-mass
energy scale than earlier in nuclear collisions. Indeed, some processes that
have been measured routinely in p+p($\overline {\rm p}$) collisions and
utilized for years in free proton PDF fits, can now finally be reached also in
the nuclear case. Such new data are expected to provide conclusive answers
concerning the universality of the nuclear PDFs. In this talk, I will contrast
some of the first p+Pb and Pb+Pb measurements to the predictions based on the
nuclear PDFs.
