Abstract

We present spectra of charged hadrons from [Formula presented] and [Formula presented] collisions at [Formula presented] measured with the BRAHMS experiment at RHIC. The spectra for different collision centralities are compared to spectra from [Formula presented] collisions at the same energy scaled by the number of binary collisions. The resulting ratios (nuclear modification factors) for central [Formula presented] collisions at [Formula presented] and [Formula presented] evidence a strong suppression in the high [Formula presented] region ([Formula presented]). In contrast, the [Formula presented] nuclear modification factor (at [Formula presented]) exhibits an enhancement of the high [Formula presented] yields. These measurements indicate a high energy loss of the high [Formula presented] particles in the medium created in the central [Formula presented] collisions. The lack of suppression in [Formula presented] collisions makes it unlikely that initial state effects can explain the suppression in the central [Formula presented] collisions.

The resulting ratios (nuclear modification factors) for central [Formula presented] collisions at [Formula presented] and [Formula presented] evidence a strong suppression in the high [Formula presented] region ([Formula presented]). In contrast, the [Formula presented] nuclear modification factor (at [Formula presented]) exhibits an enhancement of the high [Formula presented] yields.
