Higher-derivative interactions and transformation rules of the fields in the effective field theories of the massless string states are strongly constrained by space-time symmetries and dualities. Here we use an exact fo...

We compute the contact term of the two-point function for the SL (2, ℝ)- WZNW model in the winding sector. After reviewing some generalities of the model and its Euclidean counterpart, we discuss the reflection symmetr...

Generalized dualities had an intriguing incursion into Double Field Theory (DFT) in terms of local O(d, d) transformations. We review this idea and use the higher derivative formulation of DFT to compute the first order ...

We study the phase structure of the Witten-Sakai-Sugimoto model in the plane of temperature and baryon chemical potential, including the effect of a nonzero current quark mass. Our study is performed in the decompactifie...

Abstract Esophageal cancer (EC) is a malignant tumor characterized by high incidence and mortality, and its complex pathogenesis necessitates the development of effective therapeutic strategies. In this study, we investi...

We study the correlator of concentric circular Wilson loops for arbitrary radii, spatial and internal space separations. For real values of the parameters specifying the dual string configuration, a typical Gross-Ooguri ...

We consider tree-level scattering amplitudes for four string tachyons on AdS_3 imes {cal N} with pure NSNS fluxes. We show that in a small curvature expansion, properly defined, the amplitudes take the form of a genus ze...
