چکیده
Abstract We present the first calculation of scattering amplitude in singlet channel beyond QCD. The is performed SU (2) gauge theory with $$N_f=2$$ N f = 2 fundamental Dirac fermions and based on a finite-volume formalism. exhibits $$SU(4) \rightarrow Sp(4)$$ S U ( 4 ) ? p chiral symmetry breaking pattern that used to design minimal composite Higgs models currently tested at LHC. Our results show that, for range underlying fermion mass considered, lowest flavour state stable.

Sphalerons in the Standard Model with a real Higgs singlet
Sphaleron energies within the standard model with a real Higgs singlet added on are calculated. The coupled non-linear equations of motion are numerically solved and the sphaleron energy evaluated for a set of parameters in the Higgs potential. I find a small difference in the sphaleron energy compared to the standard model. A slightly stronger constraint on the strength of the first order phas...
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 کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
