The harmonic oscillator quark model for meson decays

In this paper we review the application of the harmonic oscillator quark model to the radiative and the pionic decay widths of the mesons classified according to the harmonic oscillator potential. The algebraic expressions obtained for the decay widths can be used readily to calculate the decay rates of the mesons. The computed decay rates are compared with the experimental values and reasonable agreement between the two is found, especially in the case of the transitions involving the unmixed mesons. (author)
