MEASUREMENT OF ETA(C) PRODUCTION IN UNTAGGED 2-PHOTON COLLISIONS AT LEP

Abstract:
A study of twelve distinct decay channels of the ηc has been performed with the L3 detector at LEP, for an integrated luminosity of 30 pb-1. Summing all channels, 28 candidate events have been identified, with an estimated background of 11 events. The two-photon radiative width is evaluated to be Γγγ(ηc) = 8.0 ± 2.3 ± 2.4 keV. © 1993.
