Abstract
New data on the ηη systems produced in the central pp collisions at 450 GeV/c proton beam momentum are presented. The data are obtained with the improved version of GAMS NA12/2 set-up with identification and vector momentum measurements of all particles in the final state. The tensor glueball candidate f2(2175) is confirmed. A structure in the 1.6 GeV mass region is compatible with f′2 (1525) and f0 (1590) contribution.
