Improved holographic Yang–Mills at finite temperature: Comparison with data Original Research Article

The semi-phenomenological improved holographic model for QCD is confronted with data of the pure glue, large-image gauge theory. After fitting two phenomenological parameters in the potential, the model can reproduce in detail all thermodynamic functions at finite temperature. It also reproduces in detail all known spin-0 and spin-2 glueball observables at zero temperature and predicts the rest of the image and image towers. A similar two parameter fit in the CP-odd sector postdicts the correct second image glueball mass, and predicts the rest of the image tower.
