Abstract
A search for pair-produced charged Higgs bosons is performed with the L3 de tector at LEP using data collected at centre-of-mass energies between 192 a nd 202 GeV, corresponding to an integrated luminosity of 233.2 pb(-1). Deca ys into a charm and a strange quark or into a tan lepton and its neutrino a re considered. The observed events are consistent with the expectations fro m Standard Model background processes. Including data taken at lower centre -of-mass energies, lower limits on the charged Higgs mass are derived at th e 95% confidence level. They vary from 67.4 to 79.9 GeV as a function of th e H+/- --> tau upsilon branching ratio. (C) 2000 Published by Elsevier Scie nce B.V.
