Description
The physics of different angular scales can be separated using energy-energy correlators in pp collisions. The first energy-energy correlator measurement in PbPb collisions by the CMS experiment has recently observed this also in the heavy ion environment. Significant modifications in the shape of the correlator are observed in the large angle region, which corresponds to the free quark/gluon phase of the parton shower. This part of the showers happens within quark-gluon plasma in heavy ion collisions, and the modifications cannot be explained by a simple parton energy loss. In this talk, we will explore what physics do we learn from the modifications of the large angle structures in energy-energy correlators.
