Light-cone commutators, pion amplitudes and Kl3 decay

Коммутаторы на световом конусе, пионные амплитуды иKl3 распад

Il Nuovo Cimento A (1971-1996)

Summary

Starting fromSU 3⊗SU 3 light-cone commutators a sum rule is derived for Kl3 decay. The dispersive path in the plane of the independent scalar variables is a straight line depending, essentially, onm π m K. TheSU 3 andSU 2⊗SU 2 symmetry limits, corresponding to the fixed-mass configuration, are discussed.

Riassunto

A partire da commutatori sul cono di luce dell’algebraSU 3⊗SU 3 si deriva una regola di somma per il decadimento Kl3. Il cammino dispersivo nel piano delle variabili scalari indipendenti è una retta che dipende, essenzialmente, dam π,m K. Si discutono i limiti di simmetriaSU 3 eSU 2⊗SU 2, che corrispondono alla configurazione di masse fisse.

Реэюме

Исходя иэSU 3 ⊗SU 3 коммутаторов на световом конусе, выводится правило сумм дляK l3 распада. Дисперсионный путь в плоскости неэависимых скалярных переменных представляет прямую линию, эависяшую, главным обраэом, отm π,m K. Обсуждаются пределы симметрииSU 3 иSU 2 ⊗SU 2, соответствуюшие конфигурации фиксированных масс.
