DESCRIPTION:The theoretical efforts from the past decades\, together with 
 the steadily growing available energy in Heavy-Ion (HI) colliders\, led to
  the discovery of the Quark-Gluon Plasma (QGP)\, a short-lived QCD medium 
 behaving as a hot low viscosity fluid.Being so short-lived\, the study of 
 this medium relies on a comparison between proton-proton (pp) and HI colli
 sions\, making the baseline precision\, i.e. precision of pp events\, cruc
 ial for a precise QGP estimation.Jets --- clusters of collimated particles
  sprays produced concurrently with the collision --- will be modified as t
 hey traverse this medium and can be used to access its dynamics.This work 
 delved into the jet substructure modifications arising from an improved pp
  baseline in HI collisions\, by computing the hard-scattering at NLO.To th
 is end\, a pp dijet analysis was done in the ALICE kinematical regime\, wi
 th further quenching modifications simulated using antenna-configuration b
 ased models\, in order to probe coherence effects at the substructure leve
 l.Two analysis were conducted\, one at fixed-order using MADGRAPH\, with t
 he quenching models applied to the hard-scattering NLO configuration and a
 nother one considering the full parton shower\, with the event generation 
 simulated with PYTHIA and the matched hard-scattering generated with POWHE
 G.The results show an overall agreement with ALICE data\, when considering
  the full parton shower.Moreover\, they also suggests some of the jet subs
 tructure modifications can be explained without considering any explicit b
 roadening effect.This agreement was found when using both baselines and fo
 r two parton shower algorithms\, PYTHIA default shower and VINCIA shower.Z
