The Knizhnik--Zamolodchikov structure of lattice BFKL evolution and the twist-two anomalous dimension

Josep Rubí Bort, Agustín Sabio Vera, Eduardo Serna Campillo

We study a lattice regularization of the BFKL evolution, showing its bulk dynamics is governed by an abelian Knizhnik--Zamolodchikov equation. The Hamiltonian combines long-range h…
