Rapidity dependence of high p T suppression

We present high transverse momentum hadron spectra for Au + Au and d + Au collisions at √s NN = 200GeV . The Au + Au data are obtained at pseudorapidties η = 0 and η = 2.2 and the d + Au data at η = 0. The d + Au data do not show evidence for high p T suppression, thus ruling out initial state effec...

Description
Summary:We present high transverse momentum hadron spectra for Au + Au and d + Au collisions at √s NN = 200GeV . The Au + Au data are obtained at pseudorapidties η = 0 and η = 2.2 and the d + Au data at η = 0. The d + Au data do not show evidence for high p T suppression, thus ruling out initial state effects as an explanation for the strong suppression observed in central Au + Au collisions. The suppression in central Au + Au collisions extends to the forward rapidities, which indicates that the medium responsible for the suppression is extended in the longitudinal direction.
