FIG. 1: (color online). M (τ 1 , τ 2 ) distribution for the (a) q τ 1 = q τ 2 and (b) q τ 1 = − q τ 2 samples, and (c) transverse momentum of the doubly-charged dilepton system p H T , for all four samples combined, after all selections
FIG. 2: (color online). Upper limit on the H L ±± H L ±± pair production cross section for (a) B (H L ±± → τ ± τ ± ) = 1, (b) B (H L ±± → µ ± τ ± ) = 1, and (c) B (H L ±± → τ ± τ ± ) = B (H L ±± → µ ± µ ± ) = B (H L ±± → µ ± τ ± ) = 1/3
FIG. 3: (color online). Expected and observed exclusion re- re-gion at the 95% C.L. in the plane of B (H ±± → τ ± τ ± ) versus M (H ±± ), assuming B (H ±± → τ ± τ ± ) + B (H ±± → µ ± µ ± ) = 1, for (a) left-handed and (b) right-handed H ±± bosons

A search for pair-produced charged Higgs bosons is performed with the L3 detec- tor at LEP using data collected at centre-of-mass energies between 189 and 209 GeV, corresponding to
