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 ((sic)(T)). The search uses data corresponding to 2.0 fb(-1) of integrated luminosity from p (p) over bar collisions at a center-of-mass energy of root s = 1.96 TeV, collected with the CDF II detector at the Fermilab Tevatron. From 6.697 47 x 10(6) events with a photon candidate with transverse energy E(T) > 25 GeV, we find 617 events with (sic)(T) > 25 GeV and two or more jets with 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 (sic)(T) to 50 GeV, we find 28 events versus an expectation of 30 +/- 11 events. We find no indications of non-standard-model phenomena.
