Nonet structure of theJ PC=3−− mesons

Структура нонета мезоновJ PC=3−−

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

Summary

The meson resonances g(1660),ϕ N (1650),ϕ N (1830) and KN(1760) are tentatively grouped in an «ideal»SU 3 nonet havingJ PC=3−−. A discussion of their masses and their decay modes is presented showing general agreement with the available experimental data. Our results are also discussed in the light of finite-energy, sum rules for the reactions πK → ωK and πK → ϕK.

Riassunto

Le risonanze mesoniche g(1650),ϕ N (1650),ϕ N (1830) e K N (1760) sono classificate in un nonetto «ideale» diSU 3 aventeJ PC=3−−. Si presenta una discussione delle loro masse e dei relativi modi di decadimento che risultano essere in buon accordo con i dati sperimentali a disposizione. I nostri risultati sono anche discussi alla luce di regole di somma ad energia finita applicate alle reazioni πK → ωK e πK → ϕK.

Резюме

Мезонные резонансы g(1660),ϕ N (1650),ϕ N (1830) и K N (1760), в порядке эксперимента, группируются в «идеальный»SU 3 нонет, имеющийJ PC=3−−. Проводится обсуждение их масс и мод распада, которые обнаруживают общее согласие с имеющимися экспериментальными данными. Наши результаты рассматриваются также в свете правил сумм при конечной энергии для реакций πK → ωK и πK → ϕK.
