Journal Article

We consider the Veneziano amplitude for the scattering of gluons in type IIB string theory on AdS₅ × S⁵/ℤ₂ in the presence of D7 branes. On general grounds curvature corrections around flat space can be thought of as arising from the extra insertion... Read More about Single-valuedness of the AdS Veneziano amplitude.

The AdS Veneziano amplitude at small curvature (2024)
Journal Article
Alday, L. F., Chester, S. M., Hansen, T., & Zhong, D. (2024). The AdS Veneziano amplitude at small curvature. Journal of High Energy Physics, 2024(5), Article 322. https://doi.org/10.1007/jhep05%282024%29322

We compute the AdS Veneziano amplitude for type IIB gluon scattering in AdS5 × S3 to all orders in α′ in a small curvature expansion. This is achieved by combining a dispersion relation in the dual 4dN = 2 SCFT with an ansatz for the amplitude as a w... Read More about The AdS Veneziano amplitude at small curvature.

High Energy String Scattering in AdS (2024)

We study the AdS Virasoro-Shapiro amplitude in the limit of fixed-angle high energy scattering. A recent representation as a world-sheet integral allows to compute the amplitude in this regime by saddle point techniques, very much as in flat space. T...
