Fully-resolved measurement of energy-energy correlators in 13 TeV pp collisions with the CMS experiment

Measurement of jet substructure plays a vital role in our understanding of high-energy QCD dynamics. This has traditionally been measured with various global observables such as N-subjettiness which seek to summarize the distribution of particle momenta into a single number per jet. However, there has recently been great interest in the theory community in reformulating the study of jet substructure in terms of correlators of energy flow operators. These new observables describe each jet as a distribution of energy flows and allow direct access to QCD effects such as asymptotic freedom, the confinement transition, and the dead cone effect. In this work we will discuss the challenges in measuring and unfolding these energy flow correlators and present a fully pT- and flavor-resolved measurement in 13 TeV proton-proton collisions.
