Low-energy holographic models for QCD

We consider bottom-up holographic models for quantum chromodynamics (QCD) that are constrained by the ultraviolet (UV) cutoff. Such models are supposed to exclusively describe the low-energy sector of QCD. The introduction of the UV cutoff in the soft-wall model is shown to result in a model with qualitatively different predictions. The ensuing model seems able to incorporate the constituent quark mass. We also demonstrate that in order to reproduce the results of the usual soft-wall model for the vector and higher-spin mesons in the presence of the UV cutoff, one can consider the flat bulk space with a modified dilaton background.
