Charmonium resonance production in gamma gamma collisions with the L3 detector
The production of cc states in two-photon collisions has been studied with the L3 detector at LEP. We present results on the two-photon partial widths for the resonances eta /sub c/ and chi /sub c2/, measured at square root (s) $9 approximately=91 GeV with an integrated luminosity of 140 pb/sup -1/...
