Tree string generated corrections to Einstein gravity from the sigma model approach

Abstract

We discuss the calculation of the three-loop β-function for the twodimensional non-linear σ-model with torsion. It satisfies an integrability condition which leads to the (α′)^1,2-corrections (to Einstein gravity) generated from the theory of closed bosonic strings at the tree level. Some applications of these results are briefly discussed.
