Abstract |
Vector meson photo-production in ultra-peripheral Pb-Pb collisions is sensitive to nuclear parton distribution functions, and probe models of vector meson production in nuclear interactions with strong electromagnetic fields. In pPb collisions, measurements of the Z production in the forward (pPb) and backward (Pbp) configurations are sensitive to the nPDFs in different kinematic domains, such that both probes enable complementary studies of the structure of the nucleus. In this talk, we present the latest results on charmonium production in PbPb ultra-peripheral collisions and on Z production in pPb and Pbp collisions at LHCb.
