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…

Holographic integration of $T T ˉ$ and $J T ˉ$ via $O (d, d)$

Thiago Araujo, Eoin Ó Colgáin, Yuho Sakatani +2

Prompted by the recent developments in integrable single trace $T T ˉ$ and $J T ˉ$ deformations of 2d CFTs, we analyse such deformations in the context of $A d S_{3} / C F T_{2}$ fro…

Weaving the Exotic Web

Jose J. Fernandez-Melgarejo, Tetsuji Kimura, Yuho Sakatani

String and M-theory contain a family of branes forming U-duality multiplets. In particular, standard branes with codimension higher than or equal to two, can be explicitly found as…

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…
