Mass Spectrum and Decay Rates of Charmonium and Bottomonium

The analytical studies of mass spectrum and decay rates of ground and excited states of charmonium and bottomonium in the framework of Bethe-Salpetr equation gives a detail information and understanding of the internal structure of hadrons! The main emphasis in this book was to show that the problem of 4X4 BSE under heavy-quark approximation can indeed be handled analytically for both masses as well as the wave functions in an approximate harmonic oscillator basis.
