Structure of the recoiling system in direct-photon and π^{0} production by π^{-} and p beams at 500 GeV/c

We present the results of a study of hadronic jets produced in association with direct photons and pi0's at large transverse momenta in pi-Be and pBe collisions at 500 GeV/c. Using primarily charged particles to characterize the properties of the recoiling jets, we compare their fragmentation and angular distributions, and their correlation with the trigger particle, for both the gamma and pi0 event samples. We also compare the data with QCD calculations that incorporate current parton distribution functions.
