Abstract

We present results on the search for the fourth generation quark (b'), which decays via flavor changing neutral currents (FCNC) into one photon. We have considered b'b?' production in pp? collision at center-of-mass energy of 1.8 TeV, with the integrated luminosity of 84.5 pb^(-1) . The subsequent decay of b' into a photon and jets with one b quark jet, is tagged by a soft muon. An analysis of this data gives the upper limit on Sigma x Branching Ratio at m[sub b']=100 GeV/c^(2) as 25.56 pb. This rules out the decay of b' via FCNC for m[sub b'] less than the Z mass, as the theoretically expected Sigma X Branching Ratio is 85.2 pb.
