Statistical Ensembles With Finite Bath: A Description for an Event Generator

M. Hauer, S. Wheaton

摘要:

在强子热产生的假设下,研制了一个蒙特卡罗事件发生器。在玻尔兹曼近似下,对所考虑的系统进行了大正则采样。一个重新加权计划,然后介绍占保守的电荷(重子数,奇异性,电荷)和能量和动量,有效地允许外推的巨正则结果的微正则极限。这种方法有两个强大的优势相比,分析方法和标准的微正则蒙特卡罗技术,在它是能够处理共振衰减以及(非常)大的系统尺寸。

英文摘要:

A Monte Carlo event generator has been developed assuming thermal production of hadrons. The system under consideration is sampled grand canonically in the Boltzmann approximation. A re-weighting scheme is then introduced to account for conservation of charges (baryon number, strangeness, electric charge) and energy and momentum, effectively allowing for extrapolation of grand canonical results to the microcanonical limit. This method has two strong advantages compared to analytical approaches and standard microcanonical Monte Carlo techniques, in that it is capable of handling resonance decays as well as (very) large system sizes.
