Forward Physics at STAR: Status of analysis on forward and mid rapidity   correlation measurements in p+p and d+Au
  Measurements of the production of high energy pi0 mesons at large pseudorapidity, coincident with charged hadrons at mid-rapidity, for proton+proton and deuteron+gold collisions at sqrt(s)_NN=200 GeV are reported. The p+p cross section for inclusive pi0 production follows expectations from next-to-leading order perturbative QCD. Both the inclusive cross section and the di-hadron azimuthal correlations are consistent with a model where parton showers supplement leading-order pQCD. A suppression of the back-to-back azimuthal correlations was observed in d+Au, qualitatively consistent with the gluon saturation picture.
