The search for Flavons with a mass of $\mathcal{O}$(1) TeV at current and future colliders might probe low-scale flavor models. We are interested in the simplest model that invokes the Froggatt-Nielsen (FN) mechanism with an Abelian flavor…

We compute an array of Standard Model Higgs boson ($\hsm$) signals and backgrounds for a possible upgrade of the Tevatron to $E_{\rm cm}=4\tev$. Taking $\mt\geq 140\gev$, and assuming a total accumulated luminosity of $L=30\fbi$, we find…

We consider the detection of the technirho in technicolor models that include a weak scalar doublet. In these models, the scalar develops a vacuum expectation value when the technifermions condense, and fermion masses are generated through…
We study the collider signatures of a T-odd gauge boson $W_{H}$ pair production in the Littlest Higgs Model with T-parity (LHT) at Large Hadron Collider (LHC) and Linear Collider (LC). At the LHC, we search for the $W_{H}$ boson using its…

The exiatence of extra SM families results in essential enhancement of the gluon fusion channel Higgs boson production at hadron colliders. In this case, the SM Higgs boson can be seen at the upgraded Tevatron via the "golden mode" (H-->4l)…
