Heterotic string compactifications: effective action

In this chapter we consider different aspects of the low-energy 4d effective action of heterotic compactifications. After discussing the structure of the effective action for the general CY compactifications of Chapter 7, we concentrate on the case of the abelian orbifold compactifications of Chapter 8, in which several additional aspects can be described in an explicit quantitative fashion. We discuss the form of the Kähler potential and the superpotential, as well as the gauge kinetic function and their one-loop corrections. In toroidal orbifolds the low-energy effective action must be modular invariant under T-duality transformations, and this leads to strong constraints on its structure. ...
