摘要：

We discuss recent developments on the solution of the so-called supersymmetric p-problem in the context of heterotic orbifolds. In particular, an approximate R symmetry can induce an admissible A-term in Minkowski vacua of orbifold models with the MSSM spectrum. A natural solution to the it-problem is offered by explicitly string derived NMSSMs. These models also ameliorate the fine-tuning of the MSSM. (C) 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
