Summary
The quantitative status of the\(B\bar B\) widths of true diquoniums as predicted by various models is critically analysed. It is shown that—contrary to a recent claim—unorthodox values of ≃10 MeV for the\({\mathcal{N}}\bar {\mathcal{N}}\) widths remain the most plausible ones in the framework of the3 P 0 model.
Riassunto
Si analizza criticamente lo stato quantitativo delle ampiezze\(B\bar B\) dei diquoni veri previsto da vari modelli. Si mostra che— contrariamente a una recente affermazione— i valori non ortodossi di ≃10 MeV per le ampiezze\({\mathcal{N}}\bar {\mathcal{N}}\) rimangono i piú plausibili nell’àmbito del modello3 P 0.
Резюме
Критически анализируется количественные оценки ширин\(B\bar B\) для истинных диквониумов, которые предсказываются различными моделями. Показывается, что в противоположность недавнему утверждению—неортодоксальные значения около 10 МэВ для\({\mathcal{N}}\bar {\mathcal{N}}\) ширин остаются наиболее правдоподобными в рамках3 P 0 модели.
