Abstract: We discuss light and heavy hadrons in a holographic soft-wall AdS/QCDmodel. This approach is based on an action which describes hadronstructure with broken conformal and chiral invariance and incorporatesconfinement through the presence of a background dilaton field. Accordingto the gauge/gravity duality the five-dimensional boson and fermionfields propagating in AdS space are dual to four-dimensional fieldsleaving on the surface of AdS sphere, which correspond to hadrons.In this picture hadronic wave functions --- basics blocks of hadronicproperties --- are dual to the profiles of AdS fields in the fifth(holographic) dimension, which is identified with scale variable.As applications we consider properties of light and heavy hadronsfrom unified point of view: mass spectrum, form factors, decay ratesand parton distributions. T = Light and Heavy Hadrons in AdS/QCD
