Event-by-Event Simulations of Jet Modification Using the MATTER Event Generator

Understand

The modification of hard jets in the Quark Gluon Plasma (QGP) is studied using the MATTER event generator.

• Based on the higher twist formalism of energy loss, the MATTER event generator simulates the evolution of highly virtual partons through a medium.
• These partons sampled from an underlying PYTHIA kernel undergo splitting through a combination of vacuum and medium induced emission.
• The momentum exchange with the medium is simulated via the jet transport coefficient $\hat{q}$, which is assumed to scale with the entropy density at a given location in the medium.
