英文摘要	A search for the production and non-standard decay of a Higgs boson, h, into four taus through intermediate pseudoscalars, a, is conducted on 683 pb(-1) of data collected by the ALEPH experiment at centre-of-mass energies from 183 to 209 GeV. No excess of events above background is observed, and exclusion limits are placed on the combined production cross section times branching ratio, xi(2) = sigma(e(+)e(-)-> Zh)/sigma SM(e+e--> Zh) x B(h -> aa) x B(a -> tau(+)tau(-))(2.) For m(h) < 107 GeV / c(2) and 4 < m(a) 10 GeV / c(2) , xi(2) > 1 is excluded at the 95% confidence level.
