Abstract
The 3P0 model is a typical decay model which considers only OZI-allowed strong decays and considers a quark-antiquark pair creation in the presence of the initial state meson. The quark-antiquark pair is created with the vacuum quantum numbers. This model can also be obtained from the non-relativistic limit of the pair creation Hamiltonian. Applying the Reduced Hilbert Space formalism to the pair creation Hamiltonian will produce the characteristic expansion in powers of the wave function, where the 3P0 model is the lowest order term of this expansion. This new model will correct 3P0, which we call the Corrected 3P0 model or C 3P0 model. The model will be applied to the light quarkonia decay sector.
