Y-system for form factors at strong coupling in AdS5 and with multi-operator insertions in AdS3

Understand

We study form factors in N=4 SYM at strong coupling in general kinematics and with multi-operator insertions by using gauge/string duality and integrability techniques.

• This generalizes the AdS3 results of Maldacena and Zhiboedov in two non-trivial aspects.
• The first generalization to AdS5 space was motivated by its potential connection to strong coupling Higgs-to-three-gluons amplitudes in QCD which was observed recently at weak coupling.
• The second generalization to multi-operator insertions was motivated as a step towards applying on-shell techniques to compute correlation functions at strong coupling.
