论文摘要
在超偏移式能量下PP，P-A和A-A碰撞中（抗）核产生的（抗）核的测量对于理解强环化很重要。爱丽丝的出色跟踪和粒子识别能力使其成为LHC上最适合的检测器，研究在高能强化抗碰撞中产生的光（抗）核。 （抗）质量数量高达4个的核，例如（抗）杜特隆，（抗）tritons，（anti）$^3 $ he和（anti）$^4 $，他在爱丽丝（Alice）以差异（$ | |最|η| <$ <$ 0.9）成功识别了他。在这一贡献中，出现了多样化的依赖性取决于收益率，核与蛋白质比以及合并参数$ b _ {\ mathrm a} $作为带电粒子多重性的函数的函数。
The measurement of (anti)nuclei production in pp, p-A and A-A collisions at ultrarelativistic energies is important to understand hadronization. The excellent tracking and particle identification capabilities of ALICE make it the most suited detector at the LHC to study light (anti)nuclei produced in high-energy hadronic collisions. (Anti)nuclei with mass numbers up to 4, such as (anti)deuterons, (anti)tritons, (anti)$^3$He and (anti)$^4$He have been successfully identified in ALICE at midrapidity ($|η|<$0.9). In this contribution, multiplicity dependent results on the yields, nuclei-to-protons ratios as well as the coalescence parameter $B_{\mathrm A}$ as a function of the charged-particle multiplicity are presented and compared with the expectations of coalescence and statistical hadronization models (SHM) to provide insight into their production mechanism in heavy-ion collisions.
