  Inclusive spectra of charged particles at midrapidity in Au+Au collisions at
sqrt(s_NN) = 130 GeV and 200 GeV were measured with the STAR detector at RHIC.
The measured mean transverse momentum shows a characteristic dependence on
charged particle multiplicity and beam energy in Au+Au collisions that is
distinctly different from pp, pbarp and ee collisions. A comparison with model
predictions is discussed.
