Towards a Holographic Description of QCD
📍 London

(Southampton)
Abstract:
We review AdS/CFT Correspondence constructions of non-supersymmetric theories and include quarks using D7 brane probes. Such geometries provide a geometric decription of chiral symmetry breaking in the pattern of QCD. The
meson masses of the theory can be computed and include a pion-like goldstone boson. Phenomenological models of QCD in this spirit surprisingly work at the 10-15 percent level. Finally we address a major concern with such models - they have strongly coupled UV physics. We use ideas from perfect lattice actions to suggest a solution and show a toy example of the method in action.
