INCLUSIVE PHOTONS IN p$\bar{p}$ COLLISIONS

Inclusive photon results from the Tevatron were presented, where the CDF and DØ data were seen to be consistent with each other [40]. The CDF data reach lower photon p_T values where the cross section tends to be higher than theory calculations. This shape difference is difficult to explain with current NLO QCD calculations. Best fits are obtained with the k_T smearing procedure used to explain the E706 photon data. A k_T smearing of about 3.5 GeV is needed to explain the data. The result is shown in Fig. 18.

In the same talk a high statistics measurement of photon-muon production was also presented, which compares well with NLO QCD.
