Combined analysis the experimental data on the processes &pgr;&pgr; → &pgr;&pgr;,KK¯in the channel withIGJPC= 0+0++in a model‐independent approach leads to the following results: 1) Thef0(665) state with properties of the &sgr;‐meson is proved to exist; 2) It is shown that thef0(980) and especiallyf0(1370) (if exists) have a dominantss¯component; 3) Indications for the glueball nature of thef0(1500) and for the considerabless¯component in thef0(1710) are obtained; 4) Conclusion on the linear realization of chiral symmetry (&khgr;S) is drawn. © 2002 American Institute of Physics
