1^{-+}π_{1}(1400) cannot be hybrid meson

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/104529We expose arguments concerning the π_{1}(1400) observed decaying into ηπand claimed to be an exotic meson. We conclude that this object cannot be a qqbar-g hybrid meson.4 pagesHigh Energy Physics - Phenomenology1^{-+}π_{1}(1400) cannot be hybrid mesontext
