Effective Actions Near Singularities: The STU-Model
We derive the low energy effective action of the STU-model in four and five dimensions near the line T=U, where SU(2) gauge symmetry enhancement occurs. By `integrating in' the light W^{\pm} bosons together with their superpartners, the quantum corrected effective action becomes non-singular at...
