Abstract
The "periodic table" of strongly coupled gauge theories remains only sketchily understood. Holography has developed to the point where bottom up constructions can describe the spectrum of individual gauge theories (based on assumptions of their running) including quarks in different representations and higher dimension operators. I highlight the method with a "perfected" version of an AdS dual of QCD and results for composite higgs models with two representations of quarks. The method raises questions about the degree to which energy scales can be split in generic gauge theories including whether confinement and chiral symmetry breaking are linked.
Highlights
Free gauge theories are a key element of the Standard Model of particle physics - SU(3) gauge theory describes the strong force and the SU(2) theory the weak force
They likely play a role beyond the Standard Model and possible examples include technicolour [1], composite Higgs models [2], strongly coupled dark matter [3] or dynamical supersymmetry breaking [4]
As an example of this, in [8] we in addition provided spectrum computations for twenty six of the proposed composite higgs models with top partner baryons in [32]
Summary
Free gauge theories are a key element of the Standard Model of particle physics - SU(3) gauge theory describes the strong force and the SU(2) theory the weak force They likely play a role beyond the Standard Model and possible examples include technicolour [1], composite Higgs models [2], strongly coupled dark matter [3] or dynamical supersymmetry breaking [4]. I want to show that holographic modelling of these gauge theories [7, 8] is a useful tool that can quickly provide an estimate of the spectrum These models are not first principle, they can provide a helpful exchange of ideas with lattice studies that can highlight important questions to address
