Abstract
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 (missing E(t)). The search uses data corresponding to 2.0 fb-1 of integrated luminosity from p anti-p collisions at a center-of-mass energy of s**(1/2) = 1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. From 6.69747 x 106 events with a photon candidate with transverse energy missing E(t) > 25 GeV, we find 617 events with missing E(t) > 25 GeV and two or more jets with missing E(t) > 15 GeV, at least one identified as originating from a b quark, versus an expectation of 607 +/- 113 events. Increasing the requirement on missing E(t) to 50 GeV, we find 28 events versus an expectation of 30 +/- 11 events. We find no indications of non-standard-model phenomena.
