Production of the top-pions from the higgsless-top-Higgs model at the LHC

The top-pions (πt0,±) 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.
