We have measured the transverse momentum distributions of charged hadrons in d+Au collisions at sqrt sNN = 200 GeV in the range of 0.5 < p_T < 4.0 GeV/c. The total range of pseudorapidity, eta, is 0.2 < eta < 1.4, where positive eta is in the deuteron direction. The data has been divided into three regions of pseudorapidity, covering 0.2 < eta < 0.6, 0.6 < \eta < 1.0, and 1.0 < eta < 1.4 and has been compared to charged hadron spectra from p+pbar collisions at the same energy. There is a
