The Intermediate Higgs
نویسندگان
چکیده
Two paradigms for the origin of electroweak superconductivity are a weakly coupled scalar condensate, and a strongly coupled fermion condensate. The former suffers from a finetuning problem unless there are cancelations to radiative corrections, while the latter presents potential discrepancies with precision electroweak physics. Here we present a framework for electroweak symmetry breaking which interpolates between these two paradigms, and mitigates their faults. As in Little Higgs theories, the Higgs is a pseudo-Nambu Goldstone boson, potentially composite. The cutoff sensitivity of the one loop top quark contribution to the effective potential is canceled by contributions from additional vector-like quarks, and the cutoff can naturally be higher than in the minimal Standard Model. Unlike the Little Higgs models, the cutoff sensitivity from one loop gauge contributions is not canceled. However, such gauge contributions are naturally small as long as the cutoff is below 6 TeV. Precision electroweak corrections are suppressed relative to those of Technicolor or generic Little Higgs theories. In some versions of the intermediate scenario, the Higgs mass is computable in terms of the masses of these additional fermions and the Nambu-Goldstone Boson decay constant. In addition to the Higgs, new scalar and pseudoscalar particles are typically present at the weak scale.

Associated production of Intermediate Higgs or Z-boson with t ¯ t pair in γγ collision ABSTRACT Photon-photon linear colliders can be realized by laser back-scattering technique on the next generation linear e + e − colliders. Here the associated productions of an intermediate mass Higgs (IMH) or Z-boson with t ¯ t pair in γγ collisions are studied. Since IMH is very unlikely to decay into t ¯ ...
متن کاملMore Signatures of the Intermediate Mass Higgs Boson
We examine the potential signatures of the Higgs boson when it decays into a tau-lepton pair. We show that with the proper identification of the tau-jet, this decay mode can lead to the identification of the Higgs boson over most of the intermediate mass range (MW< MH< 2 MW ).
متن کاملRoles of Higgs decay into two pseudoscalar bosons in the search of intermediate-mass Higgs Boson
The dominance of h → ηη decay mode for the intermediate mass Higgs boson is highly motivated to solve the little hierarchy problem and to ease the tension with the precision data. However, the discovery modes for mh ∼ 150 GeV, h → γγ and W/Zh → (lν/ll̄)(bb̄), will be substantially affected. We show that h → ηη → 4b is complementary and we can use this decay mode to detect the intermediate Higgs b...

We revisit the exclusive signature e(μ)+ bb̄ in the associated production of the intermediate mass Higgs boson with a W boson. We show that it is feasible to use this signature to identify the Higgs boson in the lower intermediate mass region (90 to 130 GeV) at the LHC with reasonable acceptance cuts by assuming effective bottom-jet identification. We further demonstrate that the background can ...

We present the eecient technique to extract the signal of the intermediate mass Higgs boson from the backgrounds at future colliders. For a clear Higgs detection, it is important to t the original electron accelerator energy depending on the Higgs mass, to set the polarization of the photon beams and to apply the eecient b quark tagging method. We demonstrate the extraction of information of Hi...
