A search for technipions and charged Higgs bosons at LEP
Abstract
A search has been performed for unstable charged scalar particles (S ±) such as technipions or charged Higgs bosons, pair-produced in e +e - annihilation at energies near the Z 0 pole. No evidence for such particles was observed in the decay modes e +e -→S +S -→(cs)(τv), (τv) (τv)and(cs)(cs). A lower limit (at the 95% CL ) of 35 Gev/c 2 is obtained for the mass of the charged scalar particles, independent of the branching ratio.
