Vector-like Fermions in a Minimal Composite Higgs Model
arXiv:1405.7664
Abstract
We consider the scenario where the composite Higgs arising as a pNGB in a two-site model with a non-local term included. Constraints from pion scattering and electroweak precision test are considered. We discuss the effects of composite resonances, in particular the one from composite vector-like fermions, on the oblique parameters. It is noticed that the gluon fusion production of Higgs boson is suppressed with respect to the Standard Model for about after imposing the unitarity and electroweak bounds.
