Abstract
The study of the I = 1,0(++) states with the OBELIX detector in the channel <(p)over bar p> --> (K+/-KS0) pi(-/+) at three different target densities is reported. We discuss in particular the results about a(0)(980) and the evidence of an extra scalar state with mass 1.29 +/- 0.01 GeV/c(2) and width 0.080 +/- 0.005 GeV/c(2).
