Soft Algebra for SYM
Luis F. Alday, Andrew Strominger
Scattering amplitudes of particles in nonabelian gauge theories admit factorizations of the general form $\mathcal{A}_n \;=\; \mathcal{A}^{\rm soft}_n \times \mathcal{A}^{\rm h…
Walking Sudakov: From Cusp to Octagon
Luis F. Alday, Elisabetta Armanini, Andrei V. Belitsky +2
We study the Sudakov form factor and the four-point scattering amplitude on the Coulomb branch of planar SYM as functions of the Coulomb-branch parameters and kinem…
The AdS Veneziano amplitude at small curvature
Luis F. Alday, Shai M. Chester, Tobias Hansen +1
We compute the AdS Veneziano amplitude for type IIB gluon scattering in to all orders in in a small curvature expansion. This is achieved by combining a di…
Stringy KLT Relations on
Luis F. Alday, Maria Nocchi, Aurélie Strömholm Sangaré
We study the building blocks of open and closed string amplitudes on . These are given by two infinite towers of world-sheet integrals generalising the Euler and complex beta…
From Partons to Strings: Scattering on the Coulomb Branch of SYM
Luis F. Alday, Elisabetta Armanini, Kelian Häring +1
We study scattering on the Coulomb branch of planar SYM at finite 't Hooft coupling. This setup defines a family of classical open-string S-matrices that smoothly…
Monodromy Relations for String Amplitudes on AdS
Luis F. Alday, Rodrigo S. Pitombo, Aurélie Strömholm Sangaré
We consider the Veneziano amplitude describing the scattering of four gluons in type IIB string theory on . We propose a set of powerful monodromy relations…
