Event description: 

Many New Physics searches and QCD precision measurements at particle colliders involve the study of jet substructure for final state hadrons. Recently it has been understood that measuring correlation functions of energy flow operators inside a jet can be a very powerful tool for phenomenology, which naturally stems from first principles of quantum field theory. In this talk I will present a bridge between the vast theoretical progress made to understand the energy correlators from the field theory perspective and their practical implementation into the real world of hadron colliders. I will show a factorization formula derived using soft-collinear effective theory (SCET) that makes it possible to study such energy correlators inside a jet in the complicated LHC environment. I will also show how extending such a factorization theorem to heavy quark jets presents new opportunities to observe intrinsic mass effects of elementary particles in QCD.
