Contribution
It presents a novel hybrid approach that merges weak and strong coupling physics for more accurate jet quenching modeling.
Findings
Model successfully describes LHC jet data
Combines perturbative and holographic energy loss mechanisms
Provides new insights into jet-medium interactions
Abstract
We propose a novel hybrid model for jet quenching, including both strong and weak coupling physics where each seems appropriate. Branching in the parton shower is assumed to be perturbative and described by DGLAP evolution, while interactions with the medium result in each parton in the shower losing energy as at strong coupling, as realized holographically. The medium-modified parton shower is embedded into a hydrodynamic evolution of hot QCD plasma and confronted with LHC jet data.
