In modern technicolor models, there exist very narrow spin-zero and spin-one neutral technihadrons---$pi^0_T$, $rho^0_T$ and $omega_T$---with masses of a few 100 GeV. The large coupling of $\pi^0_T$ to $\mu^+\mu^-$, the direct coupling of…

We have reconsidered the Higgs boson search via the "golden mode" for Tevatron. It is shown that this mode will give opportunity to observe the Higgs boson with mass up to 300 GeV before Tevatron shutdown.

We examine the prospects for probing heavy top quark-antiquark (t-tbar) resonances at the upgraded LHC in pp collisions at $\root_s = 14 TeV. Heavy t-tbar resonances (Z' bosons) are predicted by several theories that go beyond the standard…
