The pion decay constant as a scale for hadron dynamics

Постоянная пионного распада как масштаб для динамики адронов

Summary

We speculate on the implications of the ground-state meson decay constantf π≅93 MeV setting the scale for hadron dynamics. On this basis we conjecture that the asymptotic cross-sections obey σπN K N =f K /f π in agreement with experiment. We also find σππ=π/12f 2π ≃14 so that the pion decay constant scales the asymptotic cross-section.

Riassunto

Si specula sulle implicazioni della costante di decadimento del mesone dello stato fondamentalef π≅93 MeV che stabilisce la scala per la dinamica degli adroni. Su questa base si congettura che le sezioni d’urto asintotiche obbediscano a σπN K N =f K /f π in accordo con gli esperimenti. Si trova anche σππ=π/12f 2π ≃14 cosicché le costante di decadimento del pione riduce di scala la sezione d’urto asintotica.

Резюме

Мы обсуждаем значимость постоянной распада мезона в основном состоянииf π≅93 МэВ для установления масштаба для динамики адронов. На основе этого мы предполагаем, что асимптотические поперечные сечения удовлетворяют соотношению σπN K N =f K /f π в согласии с экспериментом. Мы также находим σππ=π/12f 2π ≃14 μд, так что постоянная пионного распада определяет масштаб асимптотического поперечного сечения.
