Abstract
The top-pions ( π t 0 , ± ) predicted by extra-dimensional descriptions of the topcolor scenario have similar feature with those in four-dimensional topcolor scenario, which have large Yukawa couplings to the third generation quarks. In the context of the higgsless–top-Higgs (HTH) model, we discuss the production of these new particles at the CERN Large Hadron Collider (LHC) via various suitable mechanisms (gluon–gluon fusion, bottom–bottom fusion, gluon–bottom fusion, and the usual Drell–Yan processes) and estimate their production rates. We find that, as long as the top-pions are not too heavy, they can be abundantly produced at the LHC. The possible signatures of these new particles might be detected at the LHC experiments.
