论文摘要
我们研究了在核子结合/重组机制中高能量碰撞中光核产生的动量依赖性。我们得出了Deuterons（$ D $）和Helions（$^3 $ HE）的动量分布的公式。我们获得了合并因子$ b_a $的分析表达式（$ d $ $ b_2 $，$ d $，$^3 $ he）作为碰撞系统大小和动量的功能。我们将推论结果应用于P-P，P-PB和PB-PB碰撞，以自然解释在CERN大型强子撞机实验中观察到的$ B_A $的有趣行为。
We study the momentum dependence of the production of light nuclei in high energy collisions in the nucleon coalescence/recombination mechanism. We derive formulas of the momentum distributions of deuterons ($d$) and helions ($^3$He). We obtain the analytic expressions of the coalescence factor $B_A$'s ($B_2$ for $d$ and $B_3$ for $^3$He) as functions of the collision system size and the momentum. We apply the deduced results to p-p, p-Pb and Pb-Pb collisions to naturally explain the interesting behaviors of $B_A$ observed in experiments at the CERN Large Hadron Collider.
