The decay of long-lived neutral kaons into two neutral pions

Распад долго-живуших нейтральных каонов на два нейтральных пиона

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

Summary

A final result is presented for a measurement of the K /0 L →2π;0 decay rate. A detailed description of the experiment and its analysis is given. The value of |η00|=(3.6±0.6)·10−3 differs by approximately 3 standard deviations from |η+−|=(1.89±0.09)·10−3. The theoretical implications of the result are discussed.

Riassunto

Si presenta un risultato finale della misura del rapporto di decadimento K /0 L →2π;0. Si riportano una dettagliata descrizione dell’esperimento e la sua analisi. Il valore di |η 00|=(3.6±0.6)·10−3 differisce di circa 3 scarti normali da |η +−|=(1.89±0.09)·10−3. Si discutono le conseguenze teoriche di questo risultato.

Реэуме

Сообшаются окончательные Реэультаты по иэмерению скорости распада K /0 L → 2π;0. Приводится подробное описание Эксперимента и его аналиэ. Величина |η 00|=(3.6±0.6)·10−3 отличается приблиэительно на 3 стандартных отклонения от |η +−=(1.89±0.9)·10−3. Обсуждаются теоретические применения Этого Реэультата.
