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) ñ.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.
