摘要：

The upcoming p + Pb run at the Large Hadron Collider (LHC) will probe the nuclear gluon distribution at very small Bjorken x (from x similar to 10(-4) at midrapidity down to x similar to 10(-6) in the proton fragmentation region) and will allow testing of approaches based on parton saturation. Here, we present the predictions of the Kharzeev-Levin-Nardi model for hadron multiplicities and multiplicity distributions in p + Pb collisions at a center-of-mass energy of 4.4 TeV. We also compare the model to the existing pp, dA, and AA data from the Relativistic Heavy Ion Collider and LHC.
