The Lightest Pseudo-Goldstone Boson at Future e + e − Colliders 1

چکیده
In a class of models of dynamical symmetry breaking not ruled out by the available data, the lightest neutral pseudo-Nambu-Goldstone boson (P ) contains only down-type techniquarks and charged technileptons. Its mass scale is naturally determined by the b-quark and therefore it is likely to be light. As the presence of pseudo-Nambu-Goldstone bosons in models of dynamical symmetry breaking is a quite general feature, the search of the P 0 at colliders is an interesting opportunity of putting limits on or discovering a dynamical electroweak symmetry breaking scenario. In this note we discuss the prospects for discovering and studying the P 0 at future e+e− and γγ colliders.

For an attractive class of dynamical symmetry breaking (technicolor) models, the lightest neutral pseudo-Nambu-Goldstone boson (P 0) contains only downtype techniquarks and charged technileptons. We discuss the prospects for discovering and studying the P 0 of such models at the Tevatron and the LHC and at future e+e− and μ+μ− colliders. Discovery of the P 0 at the Tevatron and the LHC in the g...

متن کاملPseudo Goldstones at Future Colliders from the Extended Bess
We consider the production of the lightest pseudo-Goldstone bosons at future colliders through the vector resonances predicted by the extended BESS model, which consists of an effective lagrangian parametrization with dynamical symmetry breaking, describing scalar, vector and axial-vector bound states in a rather general framework. We find that the detection of pseudo-Goldstone pairs at LHC req...
متن کاملElectroweak Symmetry Breaking by Strong Dynamics and the Collider Phenomenology ∗
We discuss the possible signatures in the electroweak symmetry breaking sector by new strong dynamics at future hadron colliders such as the Tevatron upgrade, the LHC and VLHC, and e+e− linear colliders. Examples include a heavy Higgs-like scalar resonance, a heavy Technicolor-like vector resonance and pseudo-Goldstone states, non-resonance signatures via enhanced gauge-boson scattering and fer...

We investigate the production of the lightest neutral Higgs boson in association with tau sleptons in the CP violating minimal supersymmetric standard model (MSSM) at future high-energy ee linear colliders. In parameter space of the constrained MSSM, the production cross section of ee → hτ̃ 1 τ̃ 1 can be very substantial at high energies. This process would provide a new production mechanism of n...
