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 mh < 107 GeV/c2 and 4 < ma < 10 GeV/c2, \xi^2 > 1 is excluded at the 95% confidence level.

This program is then coupled to the NMSSMTools 2.3.2 package [ref] , computing the NMSSM spectrum and checking already several phenomenological constraints: stability of the electroweak vacuum, bounds from LEP [ref] , and in particular the new Aleph limits [ref] [A bug in the corresponding version of the code for the computation of Aleph constraints was replaced by a self-made program.
