  Energy correlators measured inside high-energy jets at hadron colliders have
recently been demonstrated to provide a new window into both perturbative and
non-perturbative Quantum Chromodynamics. A number of the most interesting
features of these correlators, namely their universal scaling behavior and the
ability to image the confinement transition, require precise angular
resolution, necessitating the use of tracking information in experimental
measurements. Theoretically, tracking information can be incorporated into the
energy correlators using track functions, which are non-perturbative functions
describing the fragmentation of quarks and gluons into charged hadrons. In this
paper, we apply our recently developed track function formalism to energy
correlators, and study in detail the interplay of track functions with
perturbative resummation and non-perturbative power corrections. We provide
resummed results for the energy correlators at collinear
next-to-leading-logarithmic accuracy and compare with parton shower Monte Carlo
simulations. For the two-point correlator the use of tracking has a minimal
effect throughout the entire distribution, but it has a significant effect for
higher point correlators. Our results are crucial for the theoretical
interpretation of recent experimental measurements of the energy-energy
correlators.
