Energy-energy correlators in p-p and p-Pb collisions

Energy-energy correlators (EEC) have been proposed to study the structure of energy flow within jets. These functions are defined as the energy-weighted cross-section of particle pairs inside jets. The correlation as a function of pair distance and jet transverse momentum offers a clear separation between the perturbative and non-perturbative regimes, where one can probe the dynamics of quarks and gluons and their confinement into hadrons. I will show 2-point EECs in PYTHIA events and discuss sensitivity to cold nuclear matter effects in p-Pb collisions. We can use this to study changes to jet dynamics caused by interactions between color charges and a cold nuclear medium.
