# ${{\boldsymbol f}_{{2}}{(1910)}}$ $I^G(J^{PC})$ = $0^+(2^{+ +})$

We list here three different peaks with close masses and widths seen in the mass distributions of ${{\mathit \omega}}{{\mathit \omega}}$ , ${{\mathit \eta}}{{\mathit \eta}^{\,'}}$ , and ${{\mathit K}^{+}}{{\mathit K}^{-}}$ final states. ALDE 1991B argues that they are of different nature.
