| Abstract: | The kernel of the Schwinger-Dyson equation for a heavy-light quarkonium is studied in the limit of potential quark dynamics, and the string correction to the quark-antiquark potential is derived in agreement with the results of the quantum-mechanical QCDs tring approach. Possible ways of further improvement of the method are outlined and discussed. |
