heal.abstract	The Higgs mixing term coefficient mu(eff) is calculated in the scalar potential in supergravity theories with string origin, in a model independent approach. A general low energy effective expression is derived, where new contributions are included which depend on the modular weights q(1,2) of the Higgs superfields, the moduli and derivative terms. We find that in a class of models obtained in the case of compactifications of the heterotic superstring, the derivative terms are identically zero. Further, the total mu(eff)-term vanishes identically if the sum of the two modular weights q(1) + q(2) is equal to two. Subleading mu-corrections, in the presence of intermediate gauge symmetries predicted in viable string scenarios, are also discussed.	en
