  The multiparticle production results from A+A and p(\bar{p})+p collisions
have been compared based on the number of nucleon participants and the number
of constituent quark (parton) participants. In both normalizations, we observe
that the charged particle densities in Au+Au and Cu+Cu collisions are similar
for both \sqrt{s_{NN}} = 62.4 and 200 GeV. This implies that in symmetric
nucleus-nucleus collisions the charged particle density does not depend on the
size of the two colliding nuclei but only on the collision energy. In the
nucleon participants framework, the particle density at mid-rapidity as well as
in the limiting fragmentation region from A+A collisions are higher than those
of p(\bar{p})+p collisions at the same energy. Also the integrated total
charged particle in A+A collisions as a function of number nucleon participants
is higher than p(\bar{p})+p collisions at the same energy indicating that there
is no smooth transition between peripheral A+A and nucleon-nucleon collisions.
However, when the comparison is made in the constituent quarks framework, A+A
and p(\bar{p})+p collisions exhibit a striking degree of agreement. The
observations presented in this paper imply that the number of constituent quark
pairs participating in the collision controls the particle production. One may
therefore conjecture that the initial states A+A and p+p collisions are similar
when the partonic considerations are used in normalization. Another interesting
result is that there is an overall factorization of dN/d\eta shapes as a
function of collision centrality between Au+Au and Cu+Cu collisions at the same
energy, \sqrt{s_{NN}} = 200 GeV.
