Holographic model for hadrons in deformed AdS5 background

Several physical quantities of light hadrons are examined by a new holographic model of QCD, which is the modified version of the one proposed by Erlich et al. defined on AdS(5). In our model, AdS(5) is deformed by a non-trivial bulk scalar, this is corresponding to adding the mass term of the adjoint fermions to the 4d SYM theory dual to the gravity on AdS(5). We find that this deformation should be taken to be rather small, but its important effects are also seen. (c) 2005 Elsevier B.V. All rights reserved.
