Description of heavy vector quarkonia in the holographic approach
I.V. Pusenkov

It is well known that QCD is the only theory which can describe the physical properties of mesons doesn’t work on low energy scale. That’s why we need to study hadron models. 
The first part of this work is devoted to а phenomenological research of meson spectrum. We were able to identify a new pattern for mesons mass, depending on the number of radial excitation which describes the spectrum of deferent quarkonia in universal manner.
Second part is dedicated to investigation of two holography models. Morse holographic model is model, which shows hydrogen-like finite-state spectrum. It describes masses of light and heavy mesons quite well with tolerance 10%, which is not bad in large Nc limit.
Holographic model with three scalar fields in dual theory is the model, which gives explicit dependence on meson quark masses in spectrum. One can reproduce masses of all quarconia with accuracy less than 5%.
