Evidence for a scalar meson resonance in the π−p→nωφ reaction
2010
The charge‐exchange reaction π−p→nω(780)φ(1020) is studied with the VES setup. The (ωφ) system is observed at relatively low background. Its invariant mass distribution peaks near threshold. The two‐particles partial wave analyses shows that the Jpc = 0++ state dominates. This wave is compared with 0++ component in the (ωω) system at the comparable mass, which was measured earlier.
