论文摘要
事实证明，对PP碰撞中（抗）Deuton生产的研究是研究高能量辐射碰撞中松散结合状态的形成机制的强大工具。在本文中，使用Alice实验研究了（反）杜特龙的产生，这是$ \ sqrt {s} = 13 $ tev的无弹性PP碰撞中带电的粒子多样性的函数。由于大量累积的最小偏差事件，在PP碰撞中的（抗）deuteron产生达到相同的带电粒子多重性（$ \ rm {d} n_ {ch}/\ rm {d} n \ rm {d}η\ sim26 $），如在类似的centre-mass-mass centre ollgies中所测量的。在不确定性中，deuteron碰撞碰撞类似于p-pb相互作用中的一种，这表明在规基相互作用中产生光核的常见形成机制。在这种情况下，将测量值与聚结和统计强调模型（SHM）的期望进行了比较。
The study of (anti-)deuteron production in pp collisions has proven to be a powerful tool to investigate the formation mechanism of loosely bound states in high energy hadronic collisions. In this paper the production of (anti-)deuterons is studied as a function of the charged particle multiplicity in inelastic pp collisions at $\sqrt{s}=13$ TeV using the ALICE experiment. Thanks to the large number of accumulated minimum bias events, it has been possible to measure (anti-)deuteron production in pp collisions up to the same charged particle multiplicity ($\rm{d} N_{ch}/\rm{d}η\sim26$) as measured in p-Pb collisions at similar centre-of-mass energies. Within the uncertainties, the deuteron yield in pp collisions resembles the one in p-Pb interactions, suggesting a common formation mechanism behind the production of light nuclei in hadronic interactions. In this context the measurements are compared with the expectations of coalescence and Statistical Hadronisation Models (SHM).
