The graviton soft-wall model and the descriptions of mesons and exotic states

In this contribution, the main results of the calculations of different hadron properties, obtained within of the holographic graviton soft-wall model have been presented. In particular, the glueball, regular meson and hybrid spectra have been shown. Results are in fair agreement with experimental data, when available, and with lattice analyses. Moreover, the model has been improved to take into account the chiral-symmetry breaking mechanism to properly describe the pion within this framework.
