Twin Higgs Model
We implement a one-loop analysis of the ρ parameter in the Left Right Twin Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. Numerical results show that the one-loop contributions are dominant over the tree level corrections in most regions of parameter space. The experimentally allowed values of ρ-parameter divide the allowed parameter space ...
متن کاملA holographic composite Higgs model
Composite Higgs models [1] represent an attractive variation of the Techni-color paradigm [2]. In these theories the Standard Model (SM) Higgs doublet is the bound state of a strongly interacting sector with flavor symmetry G. It forms at a scale f π , the analog of the QCD pion decay constant, as the Goldstone boson associated with the dynamical breaking of the global symmetry G. The couplings...
متن کاملTwin Higgs Asymmetric Dark Matter.
We study asymmetric dark matter (ADM) in the context of the minimal (fraternal) twin Higgs solution to the little hierarchy problem, with a twin sector with gauged SU(3)^{'}×SU(2)^{'}, a twin Higgs doublet, and only third-generation twin fermions. Naturalness requires the QCD^{'} scale Λ_{QCD}^{'}≃0.5-20 GeV, and that t^{'} is heavy. We focus on the light b^{'} quark regime, m_{b^{'}}≲Λ_{QCD}^...
متن کاملPair production of charged Higgs bosons in the left-right twin Higgs model at the ILC
Left-Right twin Higgs(LRTH) model predicts the existence of a pair of charged Higgs φ. In this paper, we study the production of the charged Higgs bosons pair φ via the process ee → φφ at the International Linear Collider(ILC). The numerical results show that the production cross section is at the level of several tens fb, and over 10 charged scalars events can be produced at the ILC each year....
متن کاملHiggs as a Holographic Pseudo-Goldstone Boson
The AdS/CFT correspondence allows to relate 4D strongly coupled theories to weakly coupled theories in 5D AdS. We use this correspondence to study a scenario in which the Higgs appears as a composite pseudo-Goldstone boson (PGB) of a strongly coupled theory. We show how a non-linearly realized global symmetry protects the Higgs mass and guarantees the absence of quadratic divergences at any loo...
