New results on the total cross section and on charmonium formation in two photon collisions at LEP
We present new results obtained by L3 and OPAL in the measurement of the total cross section gamma gamma to hadrons. The production of the resonances eta /sub c/ and chi /sub c2/ is also discussed. (13 refs).
