Book excerpt: We present a signature-based search for 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 (/E{sub T}). The search uses data corresponding to 2.0 fb−1 of integrated luminosity from p{bar p} collisions at a center-of-mass energy of √s = 1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. From 6,697,466 events with a photon candidate with transverse energy ET > 25 GeV, we find 617 events with /E{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 /E{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.
