Hadronic Matter's Impact on Jet Energy Loss
Analysis
This paper investigates how the properties of hadronic matter influence the energy loss of energetic partons (quarks and gluons) as they traverse the hot, dense medium created in heavy-ion collisions. The authors introduce a modification to the dispersion relations of partons, effectively accounting for the interactions with the medium's constituents. This allows them to model jet modification, including the nuclear modification factor and elliptic flow, across different collision energies and centralities, extending the applicability of jet energy loss calculations into the hadronic phase.
Key Takeaways
- •Introduces a modified dispersion relation to model parton energy loss in the hadronic phase.
- •The modification is a simple multiplicative correction to the dispersion relation.
- •The model is used to describe the nuclear modification factor and elliptic flow of jets and leading hadrons.
- •The model is tested across multiple centralities and collision energies.
“The paper introduces a multiplicative $(1 + a/T)$ correction to the dispersion relation of quarks and gluons.”
