Summary
A new scheme is suggested. We demonstrate that thes-wave (p.v.) andp-wave (p.c.) amplitudes in the nonleptonic hyperon decay can be well represented by the extrapolation of the amplitudes of associated productions K1+Y→π+N \(\left( {K_1 = K^0 - \bar K^0 } \right)\) and ϰ1+Y→π+N. The model is also applied to other two-body decays. The results are good compared to the experimental data except for Λ 0− p-wave amplitude.
Riassunto
Si suggesrisce un nuovo schema. Si dimostra che le ampiezze dell'ondas (p.v.) e di quellap (p.c.) nei decadimenti di iperoni non leptonici si possono rappresentare con l'estrapolazione delle ampiezze delle produzioni associate K1+Y→π+N \(\left( {K_1 = K^0 - \bar K^0 } \right)\) e ϰ1+Y→π+N. Si applica il modello ad altri tipi di decadimento in due corpi. Il confronto dei risultati con i dati sperimentali è soddisfacente tranne che per l'ampiezza dell'ondap del Λ 0− .
Резюме
Предлагается новая схема. Мы показываем, чтоs-волновые (p.v.) и μ-волновые (p.c.) амплитуды в нелептонных распадах гиперонов могут быть представлены посредством экстраполяции амплитуд связанных рождений K1+Y→π+N \(\left( {K_1 = K^0 - \bar K^0 } \right)\). и ϰ1+Y→π+N. Модель также применяется к другим двухчастичным распадам. Результаты находятся в хорошем согласиис экспериментальными данными за исключениемp-волновой амплитуды для Λ 0− .

In the case of the pion and nucleon scattering the vector current (Δs=0) from the equal-time commutation relation eq. (9) is conserved. Equation (10) may be satisfied (depending on S.T.) and then we cannot rule out caseA and caseB for the crossing symmetry along.
Our method in the text may not be clean, but one can prove eq. (13) by direct partial integration.

Many people believe the incorrect statement that this Hamiltonian gives a zero contribution for the pion on mass shell, but nonzero for the pion off the mass shell.
N. N. Khuri (Phys. Rev.,153, 1477 (1965) has shown that the matrix elements of the scalar density do not enter into the determination of the ππ scattering lengths. We suspect it is also true in our case; nevertheless we take it as an additional assumption.
