Summary
The nonleptonic decay rates\(\Lambda _c^ + \to p\bar K^0 \) and Λ +c →Λπ+ are calculated by using current algebra and an evaluation of the matrix element by<B f |H p.c. w |B i > using nonrelativisticSU 6 wave functions. The results are found to be in good agreement with experiment. The results are also compared with earlier quark model and MIT bag model calculations.
Riassunto
Si calcolano i tassi di decadimento non leptonico\(\Lambda _c^ + \to p\bar K^0 \) e Λ +c →Λπ+ per mezzo dell’algebra delle correnti ed anche una valutazione dell’elemento di matrice<B f |H p.c. w |B i >, usando funzioni d’ondaSU 6 non relativistiche. Si trova che i risultati sono in buon accordo con l’esperimento. I risultati sono anche confrontati con precedenti calcoli del modello dei quark e del modello a sacca del MIT.
Резюме
Вычисляются интенсивности нелептонных распадов\(\Lambda _c^ + \to p\bar K^0 \) и Λ +c →Λπ+, используя алгебру току и оценку матричного элемента<B f |H p.c. w |B i > с помощью нерелятивистских волновых функций. Полученные результаты согласуются с экспериментом. Результаты также сравниваются с бычислениями в рамках модели кварков и MIT модели «мешка».
