Summary
The masses of the ground state andS andP excited states of the quark-antiquark systems for both light and heavy quarks is obtained from a relativistic potential introduced in a previous paper. The fit of the experimental data is done in terms of two-parameter potential which is a modification of Richardson potential in the line proposed by Schöberl.
Riassunto
Le masse dello stato fondamentale e degli stati eccitatiS eP dei sistemi quark-antiquark sono ottenute da un potenziale relativistico precedentemente introdotto, sia per il caso di quark leggeri che per il caso di quark pesanti. L'interpolazione dei dati sperimentali è fatta in termini di un potenziale a due parametri che risulta essere una modificazione del potenziale di Richardson nella linea proposta da Schöberl.
Резюме
Из релятивистского потенциала, введенного в предылущей статье, получаются массы основного,S иP возбужденных состояний кварк-антикварковых систем для легкого и тяжелых кварков. Проводится подгонка экспериментальных данных с помощью двух-параметрического потенциала, котопый представляет модификацию потенциала Ричардсона, предложенную щёберлом.
