Improving the Infra-red of Holographic Descriptions of QCD
arXiv:hep-ph/0603249 · doi:10.1088/1126-6708/2007/01/058
Abstract
A surprisingly good holographic description of QCD can be obtained from naive five dimensional gauge theory on a truncated AdS space. We seek to improve the infra-red description of QCD in such models by using a more sophisticated metric and an action derived from string theory duals of chiral symmetry breaking. Our metric is smooth into the infra-red and the chiral condensate is a prediction of the dynamics. The theory reproduces QCD meson data at the 10% level.
