Identified particle elliptic flow results are presented for the Au+Au reaction at (√SNN) = 200GeV as a function of transverse momentum and pseudorapidity. Data at pseudorapidities η≈ 0, 1, and 3.4 were obtained using the two BRAHMS spectrometers. Differential v2(η, pt) values for a given particle type are found to be essentially constant over the covered pseudorapidity range, in contrast to the integral v2 values which have previously been observed to decrease at forward rapidities. A softening of the particle spectra at forward angles is found to account for at least part of the integral v2 falloff. The data are found to be consistent with existing constituent quark scaling systematics.
