Abstract
Two-particle correlations of direct photon triggers with associated hadrons are obtained by isolation method in p+p collisions at \sqrt{s} = 200 GeV in PHENIX at RHIC. The initial momentum of the away-side parton is tightly constrained, because the parton-photon pair is balanced in momentum at the leading order in perturbative quantum chromodynamics (pQCD). Therefore making such correlations can be used as a tool to measure the away-side parton fragmentation function. The direct photon associated yields in p+p collisions are compared with PYTHIA and the effect of the smearing in the spectra is discussed.
