Weyl invariance of string theories in generalized supergravity backgrounds

Jose J. Fernandez-Melgarejo, Jun-ichi Sakamoto, Yuho Sakatani +1

We revisit Weyl invariance of string theories in generalized supergravity backgrounds. In the previous work arXiv:1703.09213, a possible counterterm was constructed, but it seems t…

Local $β$ -deformations and Yang-Baxter sigma model

Jun-ichi Sakamoto, Yuho Sakatani

Homogeneous Yang-Baxter (YB) deformation of AdS $_{5} \times$ S $^{5}$ superstring is revisited. We calculate the YB sigma model action up to quadratic order in fermions and show that homo…
