Radiative transitions among the vector and scalar heavy quarkonium
states with covariant light-front quark model    [PDF]

Zhi-Gang Wang

In this article, we study the radiative transitions among the vector and scalar heavy quarkonium states with the covariant light-front quark model. In calculations, we observe that the radiative decay widths are sensitive to the constituent quark masses and the shape parameters of the wave-functions, and reproduce the experimental data with suitable parameters.
