Abstract: (Springer)
In the reaction γγ→KS0KS0 resonance production of thef2− is observed. For the radiative withΓγγ.B(f2KKˉ)=0.110.02+0.03±0.02keV\Gamma _{\gamma \gamma } .B(f'_2\to K\bar K) = 0.11_{ - 0.02}^{ + 0.03}\pm 0.02keV is found. The small number of events in thef2,a2 mass region is consistent with the assumption of destructivef2−a2 interference. From the mass distribution we determine the relative phases between the tensor mesons. Upper limits on the radiative widths of the glueball candidatesf2(1720) andX (2220) are derived.
