Chiral color symmetry and possible G′-boson effects at the Tevatron and LHC
نویسندگان
چکیده
A gauge model with chiral color symmetry is considered and possible effects of the color G-boson octet predicted by this symmetry are investigated in dependence on two free parameters, the mixing angle θG and G ′ mass mG′ . The allowed region in the mG′ − θG plane is found from the Tevatron data on the cross section σtt̄ and forward-backward asymmetry A pp̄ FB of the tt̄ production. The mass limits for the G-boson are shown to be stronger than those for the axigluon. A possible effect of the G-boson on the tt̄ production at the LHC is discussed and the mass limits providing for the G-boson evidence at the LHC are estimated in dependence on θG.

The complementarity of LEP, the Tevatron and the LHC in the search for a light MSSM Higgs boson
We study the properties of the Higgs boson sector in the MSSM, putting special emphasis on radiative effects which can affect the discovery potential of the LHC, Tevatron and/or LEP colliders. We concentrate on the V bb̄ channel, with V = Z or W , and on the channels with diphoton final states, which are the dominant ones for the search for a light Standard Model Higgs boson at LEP/Tevatron and ...

We summarize results of the 1996 Snowmass workshop on future prospects for discovering dynamical electroweak symmetry breaking, compositeness, and anomalous couplings of quarks at colliders. We present the mass reach of the Tevatron to a color singlet or octet technirho, and to a topgluon or topcolor Z from topcolor assisted technicolor. We explore the sensitivity of the Tevatron, LHC, NLC, and...
متن کاملEffective Field Theory of Anomalous Gauge-boson Couplings at High-energy Pp Colliders
We compute the effects of anomalous gauge-boson couplings at high-energy hadron colliders using next-to-leading order SU(2) × SU(2) chiral perturbation theory. By comparing the yields from the universal p 2 terms with those arising from new physics at order p 4 , we estimate the sensitivity of the SSC and LHC to the indirect effects of electroweak symmetry breaking.

Any consideration of future physics facilities must be made in the context of the Tevatron and the LHC. I discuss some examples of physics results which could emerge from these machines and the resulting questions which would remain for a high energy ee collider. Particular attention is paid to the electroweak symmetry breaking sector. If a light Higgs boson exists, it will be observed at the L...
متن کاملMSSM Higgs Boson Searches at the Tevatron and the LHC: Impact of Different Benchmark Scenarios
The Higgs boson search has shifted from LEP2 to the Tevatron and will subsequently move to the LHC. The current limits from the Tevatron and the prospective sensitivities at the LHC are often interpreted in specific MSSM scenarios. For heavy Higgs boson production and subsequent decay into bb̄ or ττ, the present Tevatron data allow to set limits in the MA–tan β plane for small MA and large tanβ ...
