TY - JOUR ID - 1505624 AU - Borsato, Riccardo - Wulff, Jörgen Linus PY - 2018 TI - Non-abelian T-duality and Yang-Baxter deformations of Green-Schwarz strings JF - Journal of High Energy Physics VL - 2018 IS - 8 SP - 1-27 EP - 1-27 PB - SPRINGER SN - 10298479 KW - Sigma Models KW - String Duality KW - Superstrings and Heterotic Strings KW - Integrable Field Theories N2 - We perform non-abelian T-duality for a generic Green-Schwarz string with respect to an isometry (super)group G, and we derive the transformation rules for the supergravity background fields. Specializing to G bosonic, or G fermionic but abelian, our results reproduce those available in the literature. We discuss also continuous deformations of the T-dual models, obtained by adding a closed B-field before the dualization. This idea can also be used to generate deformations of the original (un-dualized) model, when the 2-cocycle identified from the closed B is invertible. The latter construction is the natural generalization of the so-called Yang-Baxter deformations, based on solutions of the classical Yang-Baxter equation on the Lie algebra of G and originally constructed for group manifolds and (super)coset sigma models. We find that the deformed metric and B-field are obtained through a generalization of the map between open and closed strings that was used also in the discussion by Seiberg and Witten of non-commutative field theories. When applied to integrable sigma models these deformations preserve the integrability. ER -
