摘要

A study of twelve distinct decay channels of the eta(c) 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 GAMMA(gammagamma) (eta(c)) = 8.0 +/- 2.3 +/- 2.4 keV.
