Abstract:

The search for narrow-width vector particles was undertaken using 106 pb-1 data from the collider detector at Fermilab. The cross section upper limits for narrow vector resonances decaying to tt are presented. The existence of leptophobic Z boson was not included in the top-color-assisted technicolor model at the 95% confidence level.

Abstract:

The collider detector at Fermilab was used to examine second and third generation leptoquarks. The potential production of color triplet technipions in strongly-coupled color octet technirhos decays was examined. Events with heavy flavor jets and missing energy may indicate the second-generation leptoquark decay to a charm quark and neutrino. Since there were no excess of events above standard model predictions, 95% confidence level limits were determined.
