Evidence for a0(1450)-KK-bar in proton-antiproton annihilation at rest
We present evidence for a0(1450) decaying to KK̄ in p̄p annihilation at rest in liquid hydrogen in the final state KLK±π∓. This reaction is important for the study of the KK̄ decay mode of scalar resonances, in particular the isovectors a0(980) and a0(1450). The determination of the a0(1450) product...

| description | We present evidence for a0(1450) decaying to KK̄ in p̄p annihilation at rest in liquid hydrogen in the final state KLK±π∓. This reaction is important for the study of the KK̄ decay mode of scalar resonances, in particular the isovectors a0(980) and a0(1450). The determination of the a0(1450) production also fixes the KK̄ coupling of the isoscalar f0(1500). We find B(p̄p→a0(1450)π;a0(1450)→KK̄)=(8.88±1.68)⋅10−4 and hence B(p̄p→f0(1500)π;f0(1500)→KK̄)=(4.52±0.36)⋅10−4. |
