Measurement of η<sub>c</sub> production in untagged two-photon collisions at LEP
A study of twelve distinct decay channels of the η<sub>c</sub> has been performed with the L3 detector at LEP, for an integrated luminosity of 30 pb<sup>−1</sup>. Summing all channels, 28 candidate events have been identified, with an estimated background of 11 events. The tw...

| Sumario: | A study of twelve distinct decay channels of the η<sub>c</sub> has been performed with the L3 detector at LEP, for an integrated luminosity of 30 pb<sup>−1</sup>. 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(η<sub>c</sub> ) = 8.0 ± 2.3 ± 2.4 keV. |
