Orbitally excited mass spectra of charmonium

The hadron spectroscopy is interesting due to the number of states observed experimentally. The theoretical explanation of orbitally excited state of charmonium is challenging because many states may have possibilities of exotic states. Properties like mass spectra and radiative decays are influenced by relativistic effects. The mass spectra of charmonia are calculated in the framework of quark model using relativistic correction to the kinetic energy term for the potential index 0.5 to 2.0. The decay properties are also very important to know the dynamics of the hadrons
