N-subjettiness as a jet shape to study the antenna effect in heavy-ion collisions

I hereby briefly outline the work that I have done at CERN as a Summer Student. It consisted in the characterization of a new observable called N-subjettiness, from raw level to fully corrected, as a probe for the coherence effect in the QGP environment. The data analysed are the pp and PbPb collisions detected by the ALICE experiment during LHC run 1, as well as monte carlo simulated events
