Vacuum saturation hypothesis and QCD sum rules

Гипотеза насыщения вакуума и правила сумм квантовой хромодинамики

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

The accuracy of the vacuum saturation hypothesis is discussed using the examples of vacuum expectation values of four-quark operators and the parameterB, which determines the short-distance contribution to the\(K^0 - \bar K^0 \) mixing.

Riassunto

Si discute l'accuratezza dell'ipotesi di saturazione nel vuoto usando gli esempi dei valori attesi nel vuoto degli operatori a quattro quark e il parametroB che determina il contributo a breve distanza al mescolamento\(K^0 - \bar K^0 \).

Резюме

Обсуждается точность гипотезы насыщения вакуума, используя примеры для вакуумных значений ожидания для четырех-кварковых операторов и параметраB, который опредедяет вклад на малых расстояниях в\(K^0 - \bar K^0 \) смешивание.
