Summary
We present a phenomenological analysis of the K⇒3π decay assuming a discrete symmetry like TCP or time reversal and possible PC violations. Particular attention is paid to the |ΔI|=1/2 rule and we define a four-parameter representation of the spectra corresponding to a second-order approximation of the amplitudes with respect to a convenient phase-space parameter.
Riassunto
Si conduce un’analisi fenomenologica del decadimento K⇒3π facendo l’ipotesi di una simmetria discreta come TCP, o di inversione del tempo e possibili violazioni di PC. Si rivolge particolare attenzione alla regola |ΔI|=1/2 e si definisce una rappresentazione a quattro parametri degli spettri delle ampiezze corrispondente a una approssimazione del secondo ordine rispetto a convenienti parametri dello spazio delle fasi.
Резюме
Мы представляем феноменологический анализ распада K⇒3π, предполагая дискретную симметрию, подобную TCP или обращению времени и возможные PC нарушения. Особое внимание уделяется правилу |ДI|=1/2, и мы определяем четырÿeх параметрическое представление спектра, соответствующее приближению второго порядка для амплитуд по отношению к удобному фазово-пространственному параметру.
