AdS Virasoro-Shapiro amplitude with KK modes
Giulia Fardelli, Tobias Hansen, Joao A. Silva
We determine the first curvature correction for the string amplitude of two supergravity states and two Kaluza-Klein modes on , which is dual to the…

Emergent world-sheet for the AdS Virasoro-Shapiro amplitude
Luis F. Alday, Tobias Hansen, Joao A. Silva
We construct a representation for the first AdS curvature correction to the Virasoro-Shapiro amplitude, as an integral over the Riemann sphere. The integrand is that of the Virasor…

On the spectrum and structure constants of short operators in N=4 SYM at strong coupling
Luis F. Alday, Tobias Hansen, Joao A. Silva
We study short operators in planar SYM at strong coupling, for general spin and symmetric traceless representations. At strong coupling their dimension grow…
