Abstract

The measurement of the charged-hadron transverse-momentum distributions produced in d + Au collisions was discussed. It was found that the yield at high transverse momenta increased with centrality, leading to a strong modification of the spectral shape. The changes in the spectral shape were found to be different from those in the Au + Au collisions, in terms of quality.
