STUDY OF THE KS(0)KS(0) FINAL-STATE IN 2-PHOTON COLLISIONS

Abstract:

The reaction e+e- → e+e-γ*γ * → e+e-KS0KS 0 is studied with the L3 detector at LEP and the formation of the f2′(1525) resonance is observed. For an integrated luminosity of 114 pb-1, 31±6 f2′ events are found. Their angular distribution is consistent with a pure helicity two. The radiative width times the branching ratio is measured to be Γγγ(f2′)×Br(f 2′ → KK)=(0.093±0.018±0.022) keV. Only three events are found in the f2(1270)-a2(1320) mass region, consistent with destructive f2-a2 interfer...
