Small-time behaviour and dependence of the lifetime of a particle on the measuring apparatus

Summary

Within the decay theory proposed recently which takes into account the unavoidable repeated interactions between the unstable particle and the measuring apparatus, we evaluate the dependence of the lifetime τ on the frequency of measurements λ. The model used is an exactly solvable field-theoretic model.

Riassunto

Si studia la dipendenza della vita media τ di un sistema instabile in funzione della frequenza della misura λ come proposto da una recente teoria del decadimento, usando un modello di campo esattamente risolvibile.

Резюме

Используя точно решаемую модель теории поля, исследуется зависимость времени жизни τ нестабильной системы от частоты измерений λ. Рассмотрение проводится в рамках недавно предложенной теории распада.
