Description
The Large Hadron Collider (LHC) provides an ideal environment in which to study the strong nuclear force in the high-energy regime. Studying the internal structure of jets at the LHC provides a particularly compelling opportunity to uncover the detailed dynamics of the strong force, covering a range of energy scales from the high-momentum scale of the jet itself down to the scales at which hadronization occurs. Energy-energy correlator observables are defined directly in terms of fundamental QCD operators and provide a unique window into the internal dynamics of jet formation through measurements which are amenable to relatively straightforward interpretation and first-principles calculations. We present recent measurements of this class of observables by the CMS experiment, including a new highly-differential measurement of four-point correlations inside jets. We will further discuss the practical challenges in measuring and unfolding these high-dimensional, highly-correlated data.
