If the technicolor [omega][sub T] particle exists, a likely decay mode is [omega][sub T][r arrow][gamma][pi][sub T] , followed by [pi][sub T][r arrow]b[bar b] , yielding the signature [gamma]b[bar b] . We have searched 85 pb[sup [minus]1] of data collected by the CDF experiment at the Fermilab Tevatron for events with a photon and two jets, where one of the jets must contain a secondary vertex implying the presence of a b quark. We find no excess of events above standard model expectations. We express the result as an exclusion region in the M[sub [omega][sub T]]-M[sub [pi][sub T]] mass plane.
