We have searched for evidence of physics beyond the standard
model in events that include an energetic photon and an energetic b-quark
jet, produced in 85 pb-1 of p anti-p collisions at 1.8 TeV at the Tevatron
Collider at Fermilab. This signature, containing at least one gauge boson
and a third-generation quark, could arise in the production and decay of a
pair of new particles, such as those predicted by Supersymmetry, leading to
a production rate exceeding standard model predictions. We also search
these events for anomalous production of missing transverse energy,
additional jets and leptons (e, mu and tau), and additional b-quarks. We
find no evidence for any anomalous production of gamma b or gamma b + X
events. We present limits on two supersymmetric models: a model where the
photon is produced in the decay chi-bar0_2 --> gamma chi-bar0_1, and a
model where the photon is produced in the neutralino decay into the
Gravitino LSP, chi-bar0_1 --> gamma G-bar. We also present our limits in a
model-independent form and test methods of applying model-independent
limits.
