Résumé |
We study the CFT data of planar 4D N=4 Super-Yang-Mills in the strong 't Hooft coupling limit, focusing on massive short strings in the flat-space limit of AdS5 ×S5. Specifically, we analyse the string states exchanged in the OPE of a four-point function dual to the AdS Virasoro-Shapiro amplitude. By organising this data into Regge trajectories, we predict the leading-order behaviour of four subleading trajectories using integrability, analyticity, and recent advances on the Virasoro-Shapiro amplitude. Notably, one trajectory and entire Kaluza-Klein towers decouple in the flat-space limit, hinting at an emergent selection rule for short-string scattering. Based on arXiv:2409.07529, arXiv:2310.06041, and arXiv:2306.12379. |
