Summary
We derive the slopes for the distribution of unlike and like pion energy spectra from squared matrix element. The application of the newest data to the relevant formula enables us to conclude thatCP is conserved in both theI=1 andI=2 states; therefore data of K3π are consistent with the data of |η 00| ≃ |η +−|, soCP violation comes only from the composition of K 02 and K 01 . We also present the prediction ofγ (+−0) S γ (+−0) L ≃ 10−6 if theI=2 state is zero and ≃ 10−3 if theI=2 state exists.
Riassunto
Dal quadrato degli elementi di matrice si deducono le pendenze della distribuzione degli spettri di energia dei pioni simili e dissimili. L’applicazione dei dati più recenti alla formula adatta ci permette di concludere cheCP è conservata sia nello statoI=1 che in quelloI=2; quindi i dati di K3π sono in accordo con i dati di |γ 00| ≃ |γ +−|, cosicché la violazione diCP proviene solo dalla composizione di K 02 e K 12 . Si presenta anche la predizione cheγ (+−0) S γ (+−0) L ≃ 10−6 se lo statoI=2 è nullo e ≃ 10−3 se lo statoI=2 esiste.
Реэюме
Мы выводим наклоны для распределения знергетических спектров неодинаковых и одинаковых пионов, исходя иэ квадрата матричного злемента. Применение новейщих данных в соответствуюших формулах поэволяет нам сделать вывод, что СР сохраняется в обоих состоянияхI=1 иI=2. Следовательно, данные относительно K3π согласуются с данными для |γ00| ≃ |ν+−|, а нарущениеCP проистекает только эа счет сложения K 02 и K 01 . Мы также предскаэываемγ (+−0) s γ (+−0) L ≃ 10−6, если состояниеI=2 есть нуль и зто отнощение равно ≃ 10−3, если состояниеI=2 сушествует.

Note added after this paper was completed. The latest report, byJ. Grauman, S. Taylor, E. L. Koller, D. Pandoulas, S. Hoffmaster, O. Raths, L. Romano, P. Stamer, A. Kanofsky andV. Mainkar:Phys. Rev. Lett.,23, 737 (1969), gavea(τ′ +)/a(τ +)=−2.63 ± 0.18; this is consistent with this analysis that theI=2 state has a small contribution. It is clear from eq. (33), thata(τ′ +)/a(gt +)=−2 + (−2)/λc(1/a(τ +)) · · cos (δ λ +ϕ λc ) and = −2.63 ± 0.18, and thereforec/γ ≠ 0.
