Abstract

The study of the I=1, 0++ states with the OBELIX detector in the channel p̄p→K±KS0π∓ at three different target densities is reported. We discuss in particular the initial state dependence of a0(980) production and the evidence of an extra scalar state with mass 1.29±0.01 GeV/c2 and width 0.080±0.005 GeV/c2.
