Search for anomalous production of events with a photon, jet, b -quark jet, and missing transverse energy

We present a signature-based search for the anomalous production of events containing a photon, two jets, of which at least one is identified as originating from a b quark, and missing transverse energy (Ee{sub T}). The search uses data corresponding to 2.0 fb{sup -1} of integrated luminosity from pp collisions at a center-of-mass energy of {radical}(s)=1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. From 6.697 47x10{sup 6} events with a photon candidate with transverse energy E{sub T}>25 GeV, we find 617 events with Ee{sub T}>25 GeV and two or more jets with E{sub T}>15 GeV, at least one identified as originating from a b quark, versus an expectation of 607{+-}113 events. Increasing the requirement on Ee{sub T} to 50 GeV, we find 28 events versus an expectation of 30{+-}11 events. We find no indications of non-standard-model phenomena.
