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/...

description 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/ and at square root (s) approximately=183 GeV with an integrated luminosity of 50 pb/sup -1/. The studied decay channels are eta /sub c/ to 4 pi , K/sup +/K/sup -/ $9 pi /sup +/ pi /sup -/, phi phi , K/sup 0/K/sup -or+/ pi /sup +or-/, pi /sup 0/K/sup +/K/sup -/, eta pi /sup +/ pi /sup -/, eta ' pi /sup +/ pi /sup -/, rho rho and chi /sub c2/ to J/ psi gamma.
