title = "Production of e, μ and τ pairs in untagged two-photon collisions at LEP",
abstract = "The two-photon collision reaction e+e- → e+e-l+l- has been studied at √s ≈ 91 GeV using the L3 detector at LEP for l = e, μ, τ. We have analysed untagged configurations where the two photons are quasi-real. Good agreement is found between our measurements and the script O sign(α4) QED expectation.",
