Abstract

We investigate whether known properties of the η′ meson are consistent with its being the Goldstone boson of the spontaneously broken anomaly-free R symmetry required in the light gluino scenario. We fit the masses and 2γ decays of the η and η′ mesons, and also their production in radiative J/ψ decays. We find that the η - η′ system is well-described in the light gluino scenario, if m_λ ≃ (84-144) MeV and 〈λ̄λ〉 ≃ - (0.15-0.36) GeV³. These values are in the range expected when the gluino gets its mass entirely from radiative corrections.
