Pair-production of heavy top quarks at the Tevatron Collider is significantly enhanced by the color--octet technipion, $eta_T$, occurring in multiscale models of walking technicolor. We discuss $bar tt$ rates for $m_t = 170$ GeV and $M_{eta_T} = 400-500$ GeV. Multiscale models also have color--octet technirho states in the mass range 200-600 GeV that appear as resonances in dijet production and technipion pair--production.
In the framework of topcolor-assisted technicolor model we calculate the contributions from the pseudo Goldstone bosons and new gauge bosons to $e^+e^- to tbar{t}$. We find that, for reasonable ranges of the parameters, the pseudo Goldstone bosons af
Using precision electroweak data, we put limits on ``natural top-color assisted technicolor models. Generically the new $U(1)$ gauge bosons in these models must have masses larger than roughly 2 TeV, although in certain (seemingly unrealistic) models the bound can be much lower.
The Higgs boson is produced at the LHC through gluon fusion at roughly the Standard Model rate. New colored fermions, which can contribute to $ggrightarrow h$, must have vector-like interactions in order not to be in conflict with the experimentally
We provide a pedagogical introduction to extensions of the Standard Model in which the Higgs is composite. These extensions are known as models of dynamical electroweak symmetry breaking or, in brief, Technicolor. Material covered includes: motivatio
In the context of topcolor assisted technicolor(TC2) models, we study the production of the top-pions $pi_{t}^{0,pm}$ with single top quark via the processes $pbar{p} to tpi_{t}^{0}+X$ and $pbar{p} to tpi_{t}^{pm}+X$, and discuss the possibility of d
