Holography of Strongly Coupled Gauge Theories

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.

Phases of a 10-D holographic hard wall model

“…There is also a large body of work on the properties of strongly interacting condensed matter [13,14] using holographic methods of which QCD at finite density is but a special case. Openings into the large literature on QCD related explorations of the holographic correspondence can be found in the reviews/theses [7,[15][16][17][18]. A useful resource with many references is the webpage at nLab.…”
