摘要：
We present measurements of azimuthal correlations between photons (from pi(0) decay) and charged hadrons in d+Au collisions at root s(NN)=200 GeV. We use di-hadron correlations to study parton fragmentation in d+Au collisions at RHIC. Specifically, the near-side and away-side peaks of the azimuthal angular difference distribution are used to measure the root-mean-squared (RMS) fragmentation transverse momentum root < j(T)(2)> and the mean intrinsic parton transverse momentum <vertical bar k(Ty)vertical bar >. The measurements with leading photons are compared to results using leading charged particles.
