Cross section measurement of $\tau$ pairs in two photon collisions with the L3 detector at LEP 2
The production of tau pairs in gamma gamma collisions is studied with the L3 detector at LEP. Data were collected at square root =189-202 GeV for a total integrated luminosity of 393.0 pb/sup -1/. An exclusive decay channel is considered, with tau /sup +or-/ to e/sup +or-/ nu /sub tau / nu /sub e/ a...
