Exploring the DGLAP resummation in the JIMWLK Hamiltonian / Armesto, Néstor (Santiago de Compostela U., IGFAE) ; Kovner, Alex (Connecticut U. ; Darmstadt, EMMI ; CERN) ; López-Pardo, Víctor (Santiago de Compostela U., IGFAE)
We explore the recently derived equation that resums DGLAP corrections to the JIMWLK Hamiltonian in the simplified setting of the SU(2) gauge theory. [...]
