DESCRIPTION:Energy correlations characterise the energy flux through detec
 tors at infinity produced in a collision event. In CFTs\, these detectors 
 are examples of light-ray operators and\, in particular\, the stress tenso
 r operator integrated over future null infinity. In N=4 SYM\, we combine p
 erturbation theory\, holography\, integrability\, supersymmetric localisat
 ion\, and modern conformal bootstrap techniques to obtain predictions for 
 such a collider experiment at finite coupling\, both at finite number of c
 olours\, and in the planar limit. In QCD\, the coupling runs with the angl
 e between detectors\, and there is a transition from perturbative to non-p
 erturbative QCD. In N=4 SYM\, a similar transition occurs when the couplin
 g is varied\, which we explore quantitatively. I will describe the physics
  underlying this observable and some of the methods used\, particularly in
  regimes with analytical control.
