Abstract

We discuss recent developments on the solution of the so‐called supersymmetric μ‐problem in the context of heterotic orbifolds. In particular, an approximate R symmetry can induce an admissible μ‐term in Minkowski vacua of orbifold models with the MSSM spectrum. A natural solution to the μ‐problem is offered by explicitly string derived NMSSMs. These models also ameliorate the fine‐tuning of the MSSM.
