Rigorous constraints on the derivatives ofππ s-, p- andd-wave amplitudes

Строгие ограничения на проиэводныеs, p иd парциальных ампщитудππ рассеяния

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

Summary

Constraints on the derivatives ofππ s- p- andd-wave amplitudes below threshold are deduced from crossing, positivity and twice-subtracted dispersion relations.

Riassunto

Dalle relazioni di dispersione sottratte due volte, di positività e di incrocio si deducono i vincoli delle derivate delle ampiezzeππ in ondes, p ed al di sotto della soglia.

Реэюме

Выводятся ограничения на проиэводныеs,p иd парциальных амплитуд ππ рассеяния, исходя иэ кроссинг-симметрии, положительности и дисперсионных соотнощений с двойным вычитанием.
