Fermion Resonances in Quiver Theories with a pNGB Higgs
arXiv:1408.1320 · doi:10.1007/JHEP11(2014)045
Abstract
Hierarchical quiver models can be used to build theories of electroweak symmetry breaking and natural models of flavor with a pseudo--Nambu-Goldstone boson (pNGB) Higgs. They are cousins of similar models in extra-dimensional theories in anti--de Sitter backgrounds, and can be obtained from them by coarse deconstruction. We consider the fermion excitations in these models, focusing on the quark sector and studying its generic features and phenomenology. We show that, unlike in the continuum case, the spectrum is strongly flavor dependent. To study the phenomenology of the quark excitations we compute their couplings to the Higgs sector and the gauge excitations which determine both their single-production and their decays. We show how the generic features of quiver theories with a pNGB Higgs translate, through the spectrum of quark excitations and their couplings, into a distinct phenomenology at the LHC.
