Abstract
The study of the I = 1, J(PC) = 0(++) states with the OBELIX detector in the channel (p) over bar p --> K (+/-KsT)-T-0 pi(-/+) 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).
