Some universality in brane scattering (Congkao WEN, University of London)

20.11.2025 14:00

In this talk, I will discuss some interesting features of heavy–heavy–light–light correlators in N=4 supersymmetric Yang–Mills theory, where the light operators belong to the stress-tensor multiplet and the heavy ones correspond to giant gravitons; the light operatoris realised holographically as gravitons and giant gravitons are dual to D3-branes. I will focus on the associated Integrated Correlators, for which exact expressions can be obtained despite few results being known for the correlators themselves. I will highlight several interesting properties of these integrated correlators, especially the emergence of universal structures in the strong-coupling regime. Surprisingly, the same universal strong-coupling asymptotic series govern seemingly very different integrated correlators in an N=2 superconformal field theory, which are holographically dual to gluon and graviton scatterings in the presence of D7-branes.
