Abstract:
It is shown that the O(d,d;R) deformations of the superstring vacua and the O(d,d+16;R) deformations of the heterotic string vacua preserve extended worldsheet supersymmtry. The transformtions of the complex structures are given and the action of the discrete duality subgroup is dicussed. It is shown that generic deformations do not preserve the known superfield formulations of (2,2) extended supersymmetry. The analysis is performed by decomposing the transformations in terms of the metric vielbein and by introducing space-time connections induced by the O(d,d;R) and O(d,d+16;R) deformations as a result of their non-linear action on the background fields.- string model: heterotic
