Abstract: Many New Physics searches and QCD precision measurements involve the study of jet substructure for final state hadrons. Traditionally, event shape observables have been the state of the art for studying jets, though recently it has been better 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 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 we have 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 show how extending such a factorization theorem to heavy quark jets presents new opportunities to observe intrinsic mass effects of elementary particles in QCD.

I will also discuss that it is possible to learn more about the properties of higher point energy correlators using analyticity methods developed for scattering amplitudes.  

The talk is based on ArXiv:2210.09311 and 2205.03414.
