- Descripción
- The reaction e⁺e⁻→e⁺e⁻ γ∗γ∗→e⁺e⁻ Ks⁰ Ks⁰ is studied with the L3 detector at LEP and the formation of the f₂′ (1525) resonance is observed. For an integrated luminosity of 114 pb⁻¹, 31±6 f ₂′ events are found. Their angular distribution is consistent with a pure helicity-two state. The radiative width times the branching ratio is measured to be Γ γγ (f₂′ )×Br(f₂′ →K K)=(0.093±0.018±0.022) keV. Only three events are found in the f₂ (1270)–a₂(1320) mass region, consistent with destructive f₂ –a₂ interference in the Ks⁰ Ks⁰ final state. The mixing angle of the tensor meson nonet is determined to be θ=(29.4 −1.3 +1.4 )º.
