R-symmetry and the topological twist of N=2 effective supergravities of heterotic strings
We discuss R-symmetries in locally supersymmetric N=2 gauge theories coupled to hypermultiplets which can be thought of as effective theories of heterotic superstring models. In this type of supergravities a suitable off-shell R-symmetry exists which can be used to topologically twist the theory: th...
