Resurgence of high-energy string amplitudes
Xavier Kervyn, Stephan Stieberger
We analyze the fixed-angle high-energy () structure of -point tree-level string amplitudes from complementary perspectives: locally via saddle-point expansions, a…
One-loop Double Copy Relation from Twisted (Co)homology
Pouria Mazloumi, Stephan Stieberger
We propose a geometric relation between closed and open string amplitudes at one-loop. After imposing a homological splitting on the world-sheet torus twisted intersection theory i…
One-loop Double Copy Relation in String Theory
S. Stieberger
We discuss relations between closed and open string amplitudes at one-loop. While at tree-level these relations are known as Kawai-Lewellen-Tye (KLT) and/or double copy relations,…
Open & Closed vs. Pure Open String One-Loop Amplitudes
S. Stieberger
We express one-loop string amplitudes involving both open and closed strings as sum over pure open string amplitudes. These findings generalize the analogous tree-level result to h…
