Abstract
We consider signatures at the Superconducting Super Collider of extended-technicolor (ETC) models that contain only one doublet of techniquarks. In these models, the ETC gauge bosons carry color and can be produced in the gluon-gluon subprocess of pp collisions. We find that the predominant signal is the production and decay of bound states of ETC gauge bosons. The bound-state levels are split by the hyperfine interaction and the color force. A major decay mode yields t t¯ Z0 in the final state. The bound states are expected to be narrow enough that one could observe their spectroscopy in this channel. For √s =40 TeV, the cross section times branching ratio should be about 4 nb if the ETC-boson mass is 1 TeV. The signal falls rapidly for larger masses due to the smaller effective gluon-gluon luminosity.
