Studying high-energy nuclear physics with machine learning 利用机器学习研究高能核物理
Pub Date : 2024-07-05 DOI: 10.1142/s0218301324300091

The research paradigm in physics has evolved through three distinct phases: empirical observation and induction, theoretical modeling and deduction and computational numerical analysis and simulation. We are now situated within a novel epoch wherein the scientific research paradigm is increasingly shaped by the preeminence of large-scale data and artificial intelligence, particularly within the realm of AI for science applications. The advent of high-energy colliders coupled with Monte Carlo simulations has given rise to an unprecedented accumulation of data. Nested within this transformative research paradigm, machine learning and artificial intelligence technologies have been extensively harnessed for the analysis of these vast data sets. Within the domain of high-energy nuclear physics, two prevalent machine learning techniques have emerged: Bayesian analysis and deep learning. The former employs comprehensive fitting methodologies that compare extensive data sets against theoretical models, enabling the extraction of critical information pertaining to the initial nuclear structure, parton distributions, the equation of state governing hot and dense nuclear matter, and the transport coefficients of the quark–gluon plasma, among other parameters. Conversely, the latter capitalizes on the unparalleled pattern recognition capabilities of deep learning to discern robust features from high-dimensional raw data, specifically targeting individual physical parameters. This paper elucidates the fundamental principles of machine learning and delineates its potential to augment high-energy nuclear physics research endeavors.
物理学的研究范式经历了三个不同的阶段:经验观察与归纳、理论建模与演绎以及计算数值分析与模拟。我们现在正处于一个新的时代,在这个时代里,科学研究范式日益受到大规模数据和人工智能的影响,特别是在人工智能的科学应用领域。高能对撞机和蒙特卡洛模拟的出现带来了前所未有的数据积累。在这一变革性的研究范式中,机器学习和人工智能技术被广泛用于分析这些庞大的数据集。在高能核物理领域,出现了两种流行的机器学习技术:贝叶斯分析和深度学习。前者采用综合拟合方法,将大量数据集与理论模型进行比较,从而提取与初始核结构、粒子分布、热核物质和高密度核物质的状态方程以及夸克-胶子等离子体的传输系数等参数有关的关键信息。相反,后者则利用深度学习无与伦比的模式识别能力,从高维原始数据中辨别出稳健的特征,特别是针对单个物理参数。本文阐明了机器学习的基本原理,并描述了其在增强高能核物理研究工作方面的潜力。
