Description
Jet sub-structure observables are known to be sensitive to the effects
due to mass of partons produced via hard scattering QCD interactions.
For example, QCD predicts the suppression of collinear emission around a
massive quark called dead-cone effect and it was recently observed by
the ALICE collaboration at the LHC.
In this talk, we discuss how the quark mass affect the theoretical
computations of an event shape observable such as energy-energy
correlation functions. In particular, we consider and resum the large
logarithms involving the quark mass up to next-to-leading logarithmic
approximation and study the differences between parton shower approaches
to QCD radiation by massive quarks as implemented into Pythia and Herwig
Monte Carlo event generators.
