Conformal collider physics: Energy and charge correlations

Understand

We study observables in a conformal field theory which are very closely related to the ones used to describe hadronic events at colliders.

• We focus on the correlation functions of the energies deposited on calorimeters placed at a large distance from the collision.
• We consider initial states produced by an operator insertion and we study some general properties of the energy correlation functions for conformal field theories.
• We argue that the small angle singularities of energy correlation functions are controlled by the twist of non-local light-ray operators with a definite spin.
