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)
