Query: Inclusive pi0 spectra at high transverse momentum in d-Au collisions at
  RHIC   Preliminary results on inclusive neutral pion production in d-Au collisions
at sqrt(s_NN) = 200 GeV 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 pi0
invariant differential cross sections show good agreement with next-to-leading
order (NLO) perturbative QCD calculations.
