  We present an analysis of centrality-dependent pseudorapidity distributions
of produced charged hadrons in pPb and PbPb collisions at the LHC energy of
sqrt{s_NN}=5.02 TeV, and of minimum-bias pPb collisions at 8.16 TeV within the
nonequilibrium-statistical relativistic diffusion model (RDM). In a
three-source approach, the role of the fragmentation sources is emphasized.
Together with the Jacobian transformation from rapidity to pseudorapidity and
the limiting fragmentation conjecture, these are essential for modeling the
centrality dependence. For central PbPb collisions, a prediction at the
projected FCC energy of sqrt{s_NN}=39 TeV is made.
