Search for a technicolor omega(T) particle in events with a photon and a b-quark jet at Fermilab
1999
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. {copyright} {ital 1999} {ital The American Physical Society }
