> Abstract:
>
> The charged-particle pseudorapidity density for Au+Au collisions at
> sqrt(s_NN)=62.4 GeV has been measured over a wide range of impact
> parameters and compared to results obtained at other energies.
> As a function of collision energy, the pseudorapidity distribution
> grows systematically both in height and width.  The mid-rapidity
> density is found to grow approximately logarithmically between AGS
> energies and the top RHIC energy.  As a function of centrality,
> there is an approximate factorization of the centrality dependence of
> the mid-rapidity yields and the overall multiplicity scale.  The
> new results at sqrt(s_NN)=62.4 GeV confirm the previously observed
> phenomenon of ``extended longitudinal scaling'' in the pseudorapidity
> distributions when viewed in the rest frame of one of the colliding
> nuclei.  It is also found that the evolution of the shape of the
> distribution with centrality is energy-independent, when viewed in
> this reference frame. As a function of centrality, the total charged
> particle multiplicity scales linearly with the number of participant
> pairs as it was observed at other energies.
>
> The results will be shown by Gabor Veres at the Users Meeting.  In
> accordance with our agreement we wish to submit the paper in a week's
> time.
