Inclusive $\pi^0$ spectra at high transverse momentum in d-Au collisions at RHIC

Abstract : Preliminary results on inclusive neutral pion production in d-Au collisions at $\sqrt{s_{NN}}$ in the pseudo-rapidity range $0<\eta<1$ are presented. The measurement is performed using the STAR Barrel Electromagnetic Calorimeter (BEMC). In this paper, the analysis of the first BEMC hadron measurement is described and the results are compared with earlier RHIC findings. The $\pi^0$ invariant differential cross sections show good agreement with next-to-leading order (NLO) perturbative QCD calculations.
