Curator: Nick Evans (University of Southampton),... The holographic predcictions presented on the web site are based on the model in Dynamic AdS/QCD and the Spectrum of Walking Gauge Theories Timo Alho, Nick Evans, Kimmo Tuominen (Jul 18, 2013) Published in: Phys.Rev.D 88 (2013) 105016 • e-Print: 1307.4896 [hep-ph] The 5d gauge coupling has to be set as a function of Nc and Nf. In this paper it was fitted to the spectrum at Nf=3 and allowed to go to zero at the edge of the conformal window so that the V and A sectors become degenerate and the S parameter vanishes. On this web site I more conservatively set it to the usual AdS/QCD matching condition of 24 pi^2/d(R) Nf(R). Applications to theories with multiple representaton matter are discussed in Gauge/gravity dual dynamics for the strongly coupled sector of composite Higgs models Johanna Erdmenger, Nick Evans, Werner Porod, Konstantinos S.
