Gluon and\(q\bar q\) mixing in theη−η ′−G(≡i(1440))system

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

A mixing scheme among three pseudoscalar mesons η, η′ and τ(1440) is proposed in order to analyze their\(q\bar q\) and gluonic components. Inequalities follow from requiring the consistency of the scheme and the range permitted for the mass of the pure gluonic state (glueball) turns out to be rather small. The resulting picture is in good agreement with the overall phenomenology and with the (rather scarce) data on the subject.
