Correlators with $s\ell_2$ Yangian symmetry

Understand

Correlators based on $s\ell_2$ Yangian symmetry and its quantum deformation are studied.

• Symmetric integral operators can be defined with such correlators as kernels.
• Yang-Baxter operators can be represented in this way.
• Particular Yangian symmetric correlators are related to the kernels of QCD parton evolution.
