Discovering Technicolor at Hadron Colliders

Strategies are presented for discovering light, color-singlet technipions (πT ), produced in association with a vector boson through s-channel technirho production, at the Tevatron and LHC. Signal and W+jets background were simulated including detector effects. Tagging of b-quarks from the πT → bb decay is found to be important to reduce the W+jets background. The kinematic properties of signal...

Finding Low-Scale Technicolor at Hadron Colliders

In multiscale and topcolor-assisted models of walking technicolor, relatively light spin-one technihadrons ρT and ωT exist and are expected to decay as ρT → WπT , ZπT and ωT → γπT . For MρT ≃ 200GeV and MπT ≃ 100GeV, these processes have cross sections in the picobarn range in p̄p colisions at the Tevatron and about 10 times larger at the Large Hadron Collider. We demonstrate their detectability...

TECHNICOLOR ENHANCEMENT OF tt̄ PRODUCTION AT TeV-COLLIDERS

It is shown that a technicolor theory containing a color-octet technipion, usually denoted by P 0 ′ 8 , will give rise to an enhancement of tt̄ production at the Tevatron, LHC and SSC, via the process gg → P 0′ 8 → tt̄. The relevant cross-sections are computed taking into account the large lower bound on the top mass coming from the ”top search” experiments at LEP and CDF. At the LHC and SSC, the...

γγ Physics at Linear Colliders

A high-energy lepton-lepton collider will give us a unique possibility to study eγ and γγ interactions at high energies. The high-energy photons can be generated by Compton back-scattering of laser light on the high-energy lepton beams. With slightly reduced luminosities for eγ and γγ collisions compared to the lepton-lepton collider one, unique and complementary studies can be performed. A lin...
