High-energy heavy-ion collisions provide a unique environment to study the quark–gluon plasma (QGP) through modifications of jet production. In a deconfined medium, scattering amplitudes are subtly altered, leaving measurable imprints on jet observables. Comparing these modifications with perturbative QCD predictions offers critical insight into the properties of the QGP. In this talk, I will review the theoretical framework for jet modification in a deconfined plasma, emphasizing an all-order perturbative treatment of jet observables. I will also highlight recent developments in our understanding of jet–medium interactions and their phenomenological implications.
Finally, I will discuss how these advances inform the precision of jet quenching studies and provide a foundation for future improvements in Monte Carlo event generators
