Radiative Transitions of Charmoniums within the Covariant Confined Quark Model

Radiative Transitions of Charmoniums within the Covariant Confined Quark Model

The dominant one-photon radiative transitions of the charmonium ground and orbitally excited states have been studied within an analytic confinement model. In addition to two fixed basic model parameters ( and the confinement scale ), we introduced only one adjustable parameter common to six charmon...

Zusammenfassung:The dominant one-photon radiative transitions of the charmonium ground and orbitally excited states have been studied within an analytic confinement model. In addition to two fixed basic model parameters ( and the confinement scale ), we introduced only one adjustable parameter common to six charmonium states: , , , , and to parameterize the quark distribution inside the hadron. Our estimates are in good agreement with the latest data.
