Abstract

We discuss singlet extensions of the MSSM with Z(4)(R) symmetry. We show that holomorphic zeros can avoid a potentially large coefficient of the term linear in the singlet. The emerging model has both an effective mu term and a supersymmetric mass term for the singlet mu(N) which are controlled by the gravitino mass. The mu term turns out to be suppressed against mu(N) by about one or two orders of magnitude. We argue that this class of models might provide us with a solution to the little hierarchy problem of the MSSM.
