The Energy Correlator observables probe the distributions of energy flow in the final states of particle scattering experiments. They provide valuable data for studies ranging from conformal field theories to jet substructure, and a potential playground for novel onshell methods in scattering amplitudes. 

We propose the study of the N-point energy correlators in N=4 super Yang-Mills theory, as an integrated N+1-point super form factor of protected operators with manifest dual conformal symmetry.  We present the analytic result for the four-point energy correlator in the collinear limit and comment on its singularity structures, which provide experiences for bootstrapping cross-section level observables.
