Abstract

Recent results from BRAHMS show the persistence of high suppression in Au + Au and d + Au collisions at forward rapidity. These observations have implications for Parton Energy Loss and Color Glass Condensate models. We encourage - and challenge - theorists to develop a unified description of the high suppression as it is observed in energetic heavy ion collisions at RHIC across a wide rapidity range.
