Description
The first p+Pb run at the LHC has opened a possibility to investigate the validity of the collinear factorization in a clearly higher energy scale than earlier in the 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, very recent p+Pb measurements to the predictions based on the nuclear PDFs, and discuss the insights and constraints these data offer. In particular, I will emphasize the inclusive (di)jet and $W^\pm$ production.
