A pseudoscalar field in the qq-bar interaction in heavy quarkonium

Technical Report:

Abstract

In view of the failure of all currently proposed models (and in particular those supposing a qq-bar interaction arising from the exchange of vector and scalar fields only) to simultaneously account for all the measurements of the fine structure splitting of {Chi} states in the charmonium and bottomonium systems, the results of a simple attempt to fit these measurements by introducing a pseudoscalar field is reported. In a model with a minimal number of parameters it is possible to agree with all fine structure measurements. (author) 11 refs.; 2 tabs.
