Signatures of Heavy Vectors in Higgsless models
نویسندگان
چکیده
One or more heavy spin-1 fields may replace the Higgs boson in keeping perturbative unitarity up to a few TeV while at the same time account for the electroweak precision tests. We study the Drell-Yan production of heavy vector and axial-vector states in generic Higgsless models at hadron colliders. We analyse in particular the l+l−, WZ, and three SM gauge boson final states. In the l+l− case we show how present Tevatron data restricts the allowed parameter space of these models. The two and three gauge boson final states (especially WZ, WWZ, and WZZ) are particularly interesting in view of the LHC, especially for light axial-vector masses, and could shed more light on the role of spin-1 resonances in the electroweak precision tests.

Drell-Yan production of Heavy Vectors in Higgsless models
We study the Drell-Yan production of heavy vector and axial-vector states of generic Higgsless models at hadron colliders. We analyse in particular the `+`−, WZ, and three SM gauge boson final states. In the `+`− case we show how present Tevatron data restricts the allowed parameter space of these models. The two and three gauge boson final states (especially WZ, WWZ, and WZZ) are particularly ...
متن کاملPhenomenology of Higgsless Models at the LHC and the ILC
We investigate the signatures of the recently proposed Higgsless models at future colliders. We focus on tests of the mechanism of partial unitarity restoration in the longitudinal vector boson scattering, which do not depend on any Higgsless model-building details. We study the LHC discovery reach for charged massive vector boson resonances and show that all of the preferred parameter space wi...
متن کاملHiggsless Electroweak Symmetry Breaking
In these proceedings I describe the use of tree level unitarity to constrain top quark signatures of Higgsless electroweak models and discuss implications for collider phenomenology.
متن کاملUnitarity constraints on top quark signatures of Higgsless models
We use conditions for unitarity cancellations to constrain the couplings of the top and bottom quarks to Kaluza-Klein modes in Higgsless models of electroweak symmetry breaking. An example for the mass spectrum of quark resonances in a theory space model is given and the implications for the collider phenomenology in the top sector are discussed, comparing to signatures of Little Higgs and stro...
متن کاملProduction of the top-pions from the higgsless– top-Higgs model at the LHC
The top-pions(π t ) predicted by extra dimensional descriptions of the topcolor scenario have similar feature with those in four dimensional topcolor scenario, which have large Yukawa couplings to the third generation quarks. In the context of the higgsless–top-Higgs(HTH) model, we discuss the production of these new particles at the CERN Large Hadron Collider(LHC) via various suitable mechanis...
