Abstract
The two-photon collision reaction e(+)e(-) --> e(+)e(-)l(+)l(-) has be en studied at root s approximate to 91 GeV using the L3 detector at LE P for l = e, mu, tau. We have analysed untagged configurations where t he two photons are quasi-real. Good agreement is found between our mea surements and the O(alpha(4)) QED expectation. (C) 1997 Elsevier Scien ce B.V.
