چکیده

We present an example of a realistic Higgsless model that makes use of alternative SU(2)R assignments for the top and bottom quarks recently proposed by Agashe et al. which results in an enhanced custodial symmetry. Using these new representations reduces the deviations in the Zblb̄l coupling to ∼ 4% for a wide range of parameters, while this remaining correction can also be eliminated by varying the localization parameter (bulk mass) for br.

Higgsless Standard Model in Six Dimensions

We present a Higgsless Standard Model in six dimensions, based on the Standard Model gauge group SU(2)L × U(1)Y , with two flat extra dimensions compactified on a rectangle. The electroweak symmetry is broken by (mixed) boundary conditions and realistic gauge boson masses can be accommodated by proper choice of the compactification scales and brane kinetic terms. With respect to “oblique” corre...

A Flavor Protection for Warped Higgsless Models

We examine various possibilities for realistic 5D higgsless models and construct a full quark sector featuring next-to-minimal flavor violation (with an exact bulk SU(2) protecting the first two generations) satisfying electroweak and flavor constraints. The “new custodially protected representation” is used for the third generation to protect the light quarks from flavor violations induced due...

We present a six-dimensional Higgsless Standard Model with a realistic gauge sector. The model uses only the Standard Model gauge group SU(2)L × U(1)Y with the gauge bosons propagating in flat extra dimensions compactified on a rectangle. The electroweak symmetry is broken by boundary conditions, and the correct splitting between the W and Z gauge boson masses can be arranged by suitable choice...

Phenomenology 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...
