Computation of Kℓ4 form factors with kaon PCAC and veneziano or weinberg models

Вычисление форм-факторов Kℓ4 с помошью PCAC каонов и моделей Венециано плп Вейнберга

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

Summary

We compute theF 1,F 2 form factors of Kℓ4 decay for zero square of the momentum of the lepton pair using kaon PCAC and the Kπ amplitudes of Veneziano or Weinberg models. Agreement with experiment is found to be reasonable for both models.

Riassunto

Si calcolano i fattori di formaF 1,F 2 del decadimento Kℓ4 per nn valore nullo del quadrato della quantità di moto della coppia leptonica usando PCAC del kaone e le ampiezze di Kπ dei modelli di Veneziano o di Weinberg. Per entrambi i modelli si trova un ragionevole accordo con i dati sperimentali.

Реэуме

Мы вычисляем форм-факторыF 1,F 2 для распада Kℓ4 при нулевом квадрате импульса лептонной пары, испольэуя PCAC каонов и модели Венециано или Вейнберга для Kπ амплитуд. Получается раэумное согласие с Экспериментом для обеих моделей.
