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 کاملA Composite Little Higgs Model
We describe a natural UV complete theory with a composite little Higgs. Below a TeV we have the minimal Standard Model with a light Higgs, and an extra neutral scalar. At the TeV scale there are additional scalars, gauge bosons, and vector-like charge 2/3 quarks, whose couplings to the Higgs greatly reduce the UV sensitivity of the Higgs potential. Stabilization of the Higgs mass squared parame...
متن کاملThe Minimal Composite Higgs Model
We study the idea of a composite Higgs in the framework of a five-dimensional AdS theory. We present the minimal model of the Higgs as a pseudo-Goldstone boson in which electroweak symmetry is broken dynamically via top loop effects, all flavour problems are solved, and contributions to electroweak precision observables are below experimental bounds. Since the 5D theory is weakly coupled, we ar...
متن کاملMinimal Composite Higgs Model with Light Bosons
We analyze a composite Higgs model with the minimal content that allows a light Standard-Model-like Higgs boson, potentially just above the current LEP limit. The Higgs boson is a bound state made up of the top quark and a heavy vector-like quark. The model predicts that only one other bound state may be lighter than the electroweak scale, namely a CP-odd neutral scalar. Several other composite...
