    abstract = "We present the first signature-based search for delayed photons using an
exclusive photon plus missing transverse energy final state. Events are
reconstructed in a data sample from the CDF II detector corresponding to
6: 3 fb(-1) of integrated luminosity from root s = 1.96 TeV
proton-antiproton collisions. Candidate events are selected if they
contain a photon with an arrival time in the detector larger than
expected from a promptly produced photon. The mean number of events from
standard model sources predicted by the data-driven background model
based on the photon timing distribution is 286 +/- 24. A total of 322
events are observed. A p value of 12% is obtained, showing consistency
of the data with standard model predictions."
