论文摘要
使用路径综合蒙特卡洛技术研究了四核系统在动力学冷冻条件下的聚类。该方法旨在改善以前依赖于近似半经典方法或几个体量子力学的计算。对4N系统的衰减概率进行了估计,以对各种光核衰减通道进行估计,并表征了空间相关性的强度。此外,提出了一个简单的模型,以描述该聚类对核子多重性分布的影响。还研究了由于近距离临界线(和假设的QCD临界点)对聚类的可能修改的影响。
Clustering of the four-nucleon system at kinetic freezeout conditions is studied using path-integral Monte Carlo techniques. This method seeks to improve upon previous calculations which relied on approximate semiclassical methods or few-body quantum mechanics. Estimates are given for the decay probabilities of the 4N system into various light nuclei decay channels and the strength of spatial correlations is characterized. Additionally, a simple model is presented to describe the impact of this clustering on nucleon multiplicity distributions. The effects of a possible modification of the inter-nucleon interaction due to the close critical line (and hypothetical QCD critical point) on the clustering are also studied.
