Summary
An interference model of π-π scattering is constructed which possesses linearly rising trajectories, Regge behaviour, resonances in all channels and is crossing symmetric. The model satisfies the Adler condition and predicts the Weinberg scattering lengths to within 10%. The calculated partial widths of the resonances associated with the leading trajectory are in reasonable agreement with experiment.
Riassunto
Si costruisce un modello di interferenza dello scattering ππ con traiettorie linearmente crescenti, comportamento di Regge, risonanze in tutti i canali e a simmetria incrociata. Il modello soddisfa la condizione di Adler e prevede le lunghezze di scattering di Weinberg con approssimazione del 10%. Le ampiezze parziali calcolate delle risonanze associate con la traiettoria principale sono in ragionevole accordo con i dati sperimentali.
Резюме
Конструируется интерференционная модель π-π рассеяния, которая обладает линейно возрастающими траекториями, поведением Редже, резонансами во всех каналах и является кроссинг-симметричной. Модель удовлетворяет условию Адлера и предсказывает длины рассеяння Вейнберга в пределах 10%. Вычисленные парциальные ширины резонансов, связанные с главной траекторией разумно согласуются с экспериментом.
