The measured pseudorapidity distributions of primary charged particles over a wide pseudorapidity range of |\ensuremathη|\ensuremath≤5.4 and integrated charged particle multiplicities in d+Au collisions at √sNN=200\phantom\rule0.3em0exGeV are presented as a function of collision centrality. The longitudinal features of d+Au collisions at √sNN=200\phantom\rule0.3em0exGeV are found to be very similar to those seen in p+A collisions at lower energies. The total multiplicity of charged particles is found to scale with the total number of participants according to NchdAu=(1)/(2)\ensuremath⟨Npart\ensuremath⟩Nchpp, and the energy dependence of the density of charged particles produced in the fragmentation region exhibits extended longitudinal scaling.
