THERMUS—A thermal model package for ROOT

Abstract
THERMUS is a package of C++ classes and functions allowing statistical-thermal model analyses of particle production in relativistic heavy-ion collisions to be performed within the ROOT framework of analysis. Calculations are possible within three statistical ensembles; a grand-canonical treatment of the conserved charges B, S and Q, a fully canonical treatment of the conserved charges, and a mixed-canonical ensemble combining a canonical treatment of strangeness with a grand-canonical treatm...

Title of program: THERMUS, version 2.1
Catalogue Id: AEBW_v1_0

Nature of problem
Statistical-thermal model analyses of heavy-ion collision data require the calculation of both primordial particle densities and contributions from resonance decay. A set of thermal parameters (the number depending on the particular model imposed) and a set of thermalised particles, with their decays specified, is required as input to these models. The output is then a complete set of primordial thermal quantities for each particle, together with the contributions to the final particle yields fr ...

摘要
THERMUS是一套C++类与函数集合，可在ROOT分析框架内完成相对论重离子碰撞中粒子产生过程的统计热模型分析。该工具支持三种统计系综下的计算：对守恒荷B、S和Q的巨正则处理、对守恒荷的完全正则处理，以及将奇异数的正则处理与巨正则处理相结合的混合正则系综……

程序名称：THERMUS，版本2.1
目录编号：AEBW_v1_0

问题本质
重离子碰撞数据的统计热模型分析，需同时计算原初粒子密度与共振态衰变的贡献。此类模型的输入需包含一组热参数（参数数量取决于所采用的具体模型），以及一组已指定衰变模式的热化粒子集合；模型输出则为每种粒子的完整原初热学物理量集合，以及对最终粒子产额的贡献……
