Chiral dynamics as zero-slope limit of the dual pion model

Киральная динамика как предел нулевого наклона дуальной пионной модели

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

Summary

It is shown that in taking a particular zero-slope limit (α′→0,m 2π =finite), the dual pion model reduces to a nonlinear σ-model with (1/2, 1/2) symmetry breaking in the tree approximation.

Riassunto

Si dimostra che, adottando un limite particolare di pendenza nulla (α′→0,m 2π =finito), il modello duale del pione si riduce ad un modello σ non lineare con rottura di simmetria (1/2, 1/2) nell’approssimazione ad albero.

Реэюме

Покаэывается, что при рассмотрении специального предела нулевого наклона (α′ → 0,m 2π =конечная величина) дуальная пионная модель приводит к нелинейной σ-модели с (1/2, 1/2) нарущением симметрии в древовидном приближении.
