Abstract:
0.9 using data collected between 1994 and 1995 by the
Collider Detector at Fermilab (CDF). The measurement is
based on events where the photon converts into an
electron-positron pair in the material of the inner
detector, resulting in a two track event signature. To
remove pi 0--> gamma gamma and eta --> gamma
gamma events from the data we use a new background
subtraction technique which takes advantage of the
tracking information available in a photon conversion
event. We find that the shape of the cross section as a
function of photon pT is poorly described by next-to-
leading-order QCD predictions, but agrees with previous
CDF measurements.
