Summary

Superconvergent sum rules for the processes πN → πN,\(\left( {\bar {\rm K}\Sigma \to \bar {\rm K}\Sigma } \right) + \left( {{\rm K}\Sigma \to {\rm K}\Sigma } \right)\), πΣ→пΣ and\(\left( {\bar {\rm K}\mathcal{N} \to \bar {\rm K}\mathcal{N}} \right) + \left( {{\rm K}\mathcal{N} \to {\rm K}\mathcal{N}} \right)\) have been constructed and used for predicting the Y *1 (1385) Σπ coupling.

Riassunto

Si sono costruite le regole di somma superconvergenti per i processi πN → πN,\(\left( {\bar {\rm K}\Sigma \to \bar {\rm K}\Sigma } \right) + \left( {{\rm K}\Sigma \to {\rm K}\Sigma } \right)\), πΣ→πΣ e\(\left( {\bar {\rm K}\mathcal{N} \to \bar {\rm K}\mathcal{N}} \right) + \left( {{\rm K}\mathcal{N} \to {\rm K}\mathcal{N}} \right)\) e si sono usate per predire l'accoppiamento Y *1 (1385) Σπ.

Резюме

Были сконструированы сверхсходящиеся правила сумм для процессов πN → πN,\(\left( {\bar {\rm K}\Sigma \to \bar {\rm K}\Sigma } \right) + \left( {{\rm K}\Sigma \to {\rm K}\Sigma } \right)\), πΣ → πΣ и\(\left( {\bar {\rm K}\mathcal{N} \to \bar {\rm K}\mathcal{N}} \right) + \left( {{\rm K}\mathcal{N} \to {\rm K}\mathcal{N}} \right)\), и они были использованы для предсказания связи Y *1 (1385)Σπ.
