论文摘要
抗核心被认为是空间中间接搜索暗物质（DM）歼灭的最有希望的探针之一。但是，鉴于最新的LHC PP碰撞中光反核的结果，还可以从标准模型（SM）与星际介质的标准模型（SM）碰撞中产生大量的光（抗）核。因此，需要进一步的精确测量来限制SM碰撞中反核的生产模型，以使其对其他DM歼灭事件敏感。在Proton-Proton（PP）和Proton-Proton（PP）和Proton-proton（PP）和Proton-Lead（P-Pb）colusions中，Alice合作在抗抑郁（$ \ overline {\ mathrm {d}} $）生产方面的最新结果（$^3 \ overline {\ overline {\ text {he}} $）如图所示。这些结果为目前用于估算SM背景的DM搜索的生产模型的最新计算提供了宝贵的输入。
Antinuclei are considered to be one of the most promising probes in the indirect search for dark matter (DM) annihilation in space. However, in light of recent results on the production of light antinuclei in pp collisions at the LHC, an abundant production of light (anti)nuclei is also expected from Standard Model (SM) collisions of primary cosmic rays with the interstellar medium. Hence further precise measurements are required to constrain the production models of antinuclei in SM collisions to be sensitive to additional DM annihilation events. The most recent results of the ALICE collaboration on the production of antideuterons ($\overline{\mathrm{d}}$) and antihelium-3 ($^3\overline{\text{He}}$) in proton-proton (pp) and proton-lead (p--Pb) collisions are shown. These results provide valuable input for state-of-the-art calculations of the production models currently used to estimate the SM background to DM searches.
