New Measurements with Photons at the Tevatron
  We present three recent photon analyses from data collected at the Fermilab Tevatron: measurements of the direct photon pair production cross section at CDF and D0, measurements of azimuthal decorrelations and multiple parton interactions in gamma + 2 jet and gamma + 3 jet events at D0, and an observation of exclusive diphoton production at CDF.
