论文摘要
近年来，爱丽丝广泛研究了不同碰撞系统和质量中心能量中光（抗）核的产生。然而，光（超级）核的生产机制仍然不清楚，并且在科学界的激烈争论。两类模型通常用于描述核产生：统计强调模型和结合模型。在重型离子碰撞中，这两个模型都很好地描述了光核的产量及其与哈德子的产量的比率，因此很难区分两者。相反，由于不同预测之间的较大分离，因此小型碰撞系统（例如PP和P-PB碰撞）非常适合研究（反）（超）核生产机制。在本文中，在核合成模型的背景下讨论了小型碰撞系统中用爱丽丝在LHC上测得的光核产生的结果，使我们能够排除SHM和合并模型的某些配置，以便将更严格的约束设置为可用的理论预测。
In recent years, ALICE has extensively studied the production of light (anti)(hyper)nuclei in different collision systems and center-of-mass energies. Nevertheless, the production mechanisms of light (hyper)nuclei is still unclear and under intense debate in the scientific community. Two classes of models are typically used to describe nuclear production: the statistical hadronisation model and the coalescence ones. In heavy-ion collisions, both models describe well the production yields of light nuclei and their ratios to the yields of hadrons, making it difficult to distinguish between the two. On the contrary, small collision systems, such as pp and p-Pb collisions, are ideal to study the (anti)(hyper)nuclei production mechanisms, thanks to the large separation between the different predictions. In this paper, recent results on light nuclei production measured with ALICE at the LHC in small collision systems are discussed in the context of the nucleosynthesis models, allowing us to exclude some configurations of the SHM and coalescence models in order to set tighter constraints to the available theoretical predictions.
