The field of hadron physics contains the study of strongly interacting matter in all its manifestations and understanding of its properties and interactions in terms of the un- derlying fundamental theory, Quantum Chromodynamics (QCD). The primary goal of hadron physics are to determine the relevant degrees of freedom that govern the hadron phenomena at all scales, to establish the connection of these degrees of freedom to the parameters and fundamental fields of QCD, to quantitatively describe a wide array of hadron phenomena ranging from its spectroscopy to their decay properties. Spectroscopy is a powerful tool in physics as it provides a mean to understand the es- sential degree of freedom involved in molecules, atoms, nucleus and the hadrons.
