Query: Dijets in p+Pb collisions and their quantitative constraints for nuclear
  PDFs   We present a perturbative QCD analysis concerning the production of high-pT
dijets in p+Pb collisions at the LHC. The next-to-leading order corrections,
scale variations and free-proton PDF uncertainties are found to have only a
relatively small influence on the normalized dijet rapidity distributions.
Interestingly, however, these novel observables prove to retain substantial
sensitivity to the nuclear effects in the PDFs. Especially, they serve as a
more robust probe of the nuclear gluon densities at $x>0.01$, than e.g. the
inclusive hadron production. We confront our calculations with the recent data
by the CMS collaboration. These preliminary data lend striking support to the
gluon antishadowing similar to that in the EPS09 nuclear PDFs.
