BFKL Spectrum of N=4 SYM: non-Zero Conformal Spin

Understand

We developed a general non-perturbative framework for the BFKL spectrum of planar N=4 SYM, based on the Quantum Spectral Curve (QSC).

• It allows one to study the spectrum in the whole generality, extending previously known methods to arbitrary values of conformal spin $n$.
• We show how to apply our approach to reproduce all known perturbative results for the Balitsky-Fadin-Kuraev-Lipatov (BFKL) Pomeron eigenvalue and get new predictions.
• In particular, we re-derived the Faddeev-Korchemsky Baxter equation for the Lipatov spin chain with non-zero conformal spin reproducing the corresponding BFKL kernel eigenvalue.
