Artist’s rendering of QGP formation in a nuclear collision at RHIC, in which a high-energy photon (purple line) and jet of correlated particles (cone) propagate back-to-back in the QGP. Jet scattering in the QGP broadens the distribution of their azimuthal opening angle. Plot showing a comparison between universal model predictions for the energy-energy correlators in jets and ALICE measurements. A collection of 4 scientific instruments in circles representing the Physical Sciences Area Logo photograph of the group of participants of the summer school.
