Jets are the experimental proxies for the hard sca ttered partons\, convoluting both their perturbative and non-perturbative Quantum Chromodynamics (QCD) evolution. Depending on the collision system\ , the outgoing partons can either traverse what we actually call a “QCD vacuum”\, as in deep inelastic scatterings (DIS) or proton-proton collis ions\, or a new\, highly complex state of matter - the quark-gluon plasma (QGP)\, produced in heavy-ion collisions (HICs). This medium evolves concu rrently with the hard partons\, further convoluting HIC jets with QGP-indu ced effects.Our research aims to use jet substructure to disentangle these effects and probe QCD across different environments and energy scales. We employ substructure-based jet selections in electron-proton DIS to enhanc e sensitivity to non-perturbative effects\, moving towards constraining cu rrently existing phenomenological models to describe hadronization. Furthe rmore\, a detailed characterization of jet quenching\, i.e. the modificati on of jets in the presence of a QGP\, has the potential to unlock a compre hensive tomographic description of the QGP. We explore novel jet substruct ure observables based on energy correlations to quantify jet quenching acr oss angular scales.

In ultra-relativist ic particle collisions\, such as those performed at RHIC and LHC\, quarks and gluons (partons) can be scattered with large transverse momenta and su bsequently evolve into collimated sprays of hadrons known as jets. Jets ar e the experimental proxies for the hard scattered partons\, convoluting bo th their perturbative and non-perturbative Quantum Chromodynamics (QCD) ev olution. Depending on the collision system\, the outgoing partons can eith er traverse what we actually call a “QCD vacuum”\, as in deep inelasti c scatterings (DIS) or proton-proton collisions\, or a new\, highly comple x state of matter - the quark-gluon plasma (QGP)\, produced in heavy-ion c ollisions (HICs).


This medium evolves concurrently with the hard partons\, further convoluting HIC jets with QGP-induced effects.
Our research aims to use jet substructure to disentangle these effects an d probe QCD across different environments and energy scales.

We employ substructure-based jet selections in electron-proton DIS to enhance sensitivity to non-perturbative effects\, moving towards constraining cur rently existing phenomenological models to describe hadronization. Further more\, a detailed characterization of jet quenching\, i.e. the modificatio n of jets in the presence of a QGP\, has the potential to unlock a compreh ensive tomographic description of the QGP. We explore novel jet substructu re observables based on energy correlations to quantify jet quenching acro ss angular scales.
