The LHCb detector’s forward geometry provides unprecedented access to the very low regions of Bjorken x inside the nucleon. LHCb is able to study charged and neutral light hadron production, as well as relatively rare probes such as heavy quark. These data provide unique constraints on nuclear parton distributions. This contribution will discuss recent LHCb measurements sensitive to the low-x structure of nucleons, and discuss the impact of recent LHCb measurements on global analyses of nuclear parton distributions
Because of the increasing gluon density towards small-𝑥, a regime where these densities reach a saturation (𝑄sat) is expected. The observation of this gluon saturated matter has several consequences to particle production and is a matter of an entire effective field theory, the Color Glass Condensate. The Large Hadron Collider beauty (LHCb) experiment has a privileged geometry for the search of the gluon saturation achieving an unprecedent small-𝑥 coverage. The most direct measurement of gluon densities and kinematics in hadronic collisions is the inverse Compton process (𝑞+𝑔→𝛾+𝑞). The LHCb experiment measured pairs of isolated photons correlated with hadrons from the quark fragmentation in pPb and Pbp collisions at 8.16 TeV probing a Bjorken-𝑥 between 10^{-5}
