相对论性重离子碰撞的事件generator

MARTINI: An event generator for relativistic heavy-ion collisions

Bjoern Schenke, Charles Gale, Sangyong Jeon

摘要:

我们介绍了模块化算法的相对论治疗重IoN相互作用(MARTINI),一个全面的事件发生器的硬和穿透探针在高能核-核碰撞。它的主要组成部分是软背景的时间演化模型,PYTHIA 8.1和McGill-AMY部分子演化方案,包括辐射和弹性过程。这使我们能够在高p_T区产生考虑热QCD和QED效应以及演化介质效应的全事件组态。本文给出了RHIC上Au+Au碰撞中性π核修正因子在不同中心度下随p_T的变化,以及在非中心碰撞中随相对于反应平面的夹角的变化。此外,我们研究了高横动量光子的生产纳入一套完整的光子生产渠道。

英文摘要:

We introduce the Modular Algorithm for Relativistic Treatment of heavy IoN Interactions (MARTINI), a comprehensive event generator for the hard and penetrating probes in high energy nucleus-nucleus collisions. Its main components are a time evolution model for the soft background, PYTHIA 8.1 and the McGill-AMY parton evolution scheme including radiative as well as elastic processes. This allows us to generate full event configurations in the high p_T region that take into account thermal QCD and QED effects as well as effects of the evolving medium. We present results for the neutral pion nuclear modification factor in Au+Au collisions at RHIC as a function of p_T for different centralities, and also as a function of the angle with respect to the reaction plane for non-central collisions. Furthermore, we study the production of high transverse momentum photons incorporating a complete set of photon-production channels.
