MARTINI - Monte Carlo simulation of jet evolution

Bjoern Schenke, Charles Gale, Sangyong Jeon

摘要:

我们提出了模块化算法的相对论治疗重IoN相互作用(MARTINI),事件发生器的硬和穿透探针在高能核-核碰撞。模拟由软背景的时间演化模型组成,如流体力学,PYTHIA 8.1在介质演化后产生和强子化硬部分子,该模型基于McGill-AMY形式主义,包括辐射和弹性过程。MARTINI允许在高横向动量区域产生完整的事件配置。给出了RHIC上Au+Au碰撞中中性π介子和光子核修正因子的计算结果。

英文摘要:

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.
