Abstract

We present preliminary results for Cu+Cu collisions at at the BRAHMS experiment from charged hadron spectra and nuclear modification factors as a function of centrality and pseudo-rapidity. Deviations from binary scaling at intermediate and high-p_T reveal themselves as a suppression in the transverse momentum distribution of produced particles. The observed suppression depends on the volume of the interaction region through which produced hadrons have to travel. While there is still significant suppression, R_cp seems to depend very little on pseudo-rapidity.
