published as Phys.Lett.B606:303-312,2005 · Discussion of the different approximations to 3+1D plasma expansion and their impact on the energy loss calculation is added. The relation between the quenching of the single and double inclusive spectra is also clarified and shown in the right panel of Figure 2. 7 pages, 2 figures

The final state energy loss of fast partons penetrating a longitudinally expanding quark–gluon plasma of effective gluon rapidity density dNg/dy=650–800 is evaluated and incorporated together with the multiple initial state Cronin scattering in the lowest order perturbative QCD hadron production formalism. Predictions for the neutral pion attenuation in central Au + Au collisions at the intermediate RHIC energy of sNN=62GeV relative to the binary collision scaled p+p result are given. The quenching is found to be a factor of 2–3 with a moderate transverse momentum dependence and the attenuation of the away side di-hadron correlation function is estimated to be 3–5-fold.
