Abstract: (Elsevier)
The study of the I =1, J PC =0 ++ states with the OBELIX detector in the channel p ̄ p→K ± K 0 S π ∓ at three different target densities is reported. The data show the evidence for an extra scalar state with mass 1.29±0.01 GeV/ c 2 and width 0.080±0.005 GeV/ c 2 .- anti-p p: annihilation
- hydrogen: density
- at rest
- scalar meson: search for
- scalar meson: isovector
- final state: (K0(S) K pi)
- mass spectrum
- angular momentum
- Dalitz plot
- partial wave analysis
