MARTINI - Monte Carlo simulation of jet evolution

TL;DR

MARTINI is a comprehensive Monte Carlo event generator that models jet evolution in heavy-ion collisions, integrating hydrodynamics and parton interactions to simulate high-energy nuclear events.

Contribution

It introduces a modular framework combining hydrodynamics and parton energy loss formalism for detailed jet evolution simulation.

Findings

Neutral pion and photon nuclear modification factors in Au+Au collisions at RHIC.

Full event configurations for high transverse momentum regions.

Inclusion of radiative and elastic processes in jet evolution.

Abstract

We present the Modular Algorithm for Relativistic Treatment of heavy IoN Interactions (MARTINI), an event generator for the hard and penetrating probes in high energy nucleus-nucleus collisions. The simulation consists of a time evolution model for the soft background, such as hydrodynamics, PYTHIA 8.1 to generate and hadronize the hard partons after the medium evolution, which is based on the McGill-AMY formalism and includes both radiative and elastic processes. MARTINI allows for the generation of full event configurations in the high transverse momentum region. We present results for the neutral pion and photon nuclear modification factor in Au+Au collisions at RHIC.
