Direct Photons at D0 and CDF:

New Results from the Tevatron Collider

Talk given at the `hadronic' Moriond, Les Arcs, France, 22-29 March 1997.

Stefan Grünendahl

University of Rochester

Many thanks to Wei Chen (D0 diphotons), Jodi Lamoureux (CDF photon + 2 jets), Takeshi Takano (CDF diphotons), and everybody else who provided input. The 'Photon Production at the Collider' graphics was made by John Womersley. (Note to D0 collaborators: Postscript files for all of the source materials used in this talk, including John's drawing, can be found on the D0 PC network, under //darkstar/morio97.)

Link to the rather large (4.2 MB) postscript file.
