论文摘要
对浅口和重味重质的生产的研究对于表征在超旧式重型离子碰撞中产生的党派阶段至关重要，并研究了LHC的强发机制。在pb和pp碰撞中进行的研究揭示了意外的特征，在质量上与较大的碰撞系统中观察到的研究相似，在魅力部门中，与$ {\ rm e}^{+} {+} {\ rm e} {\ rm e} {\ rm e}^{ - }^{ - } $ and $ e} $ {\ rm e}^pre n n of $ {\ rm e}^{+rm e} {\ rm e}^{p p} =爱丽丝实验已经利用了其出色的跟踪和颗粒识别能力，直至低横向动量，以对质子，超子和诱人的重子进行广泛的研究。在本文中，介绍了对光（质子和超子）以及重味$（λ_{\ rm c}）$ baryon生产的最新结果的讨论，并与现象学模型进行了比较。
Studies of the production of light- and heavy-flavor baryons are of prominent importance to characterize the partonic phase created in ultrarelativistic heavy-ion collisions and to investigate hadronization mechanisms at the LHC. Studies performed in p-Pb and pp collisions have revealed unexpected features, qualitatively similar to what is observed in larger collision systems and, in the charm sector, not in line with the expectations from ${\rm e}^{+}{\rm e}^{-}$ and ${\rm e}^{-}{\rm p}$ interactions. The ALICE experiment has exploited its excellent tracking and particle identification capabilities down to low transverse momentum to perform an extensive study of protons, hyperons and charmed baryons. In this paper, a discussion of the most recent results on light (protons and hyperons) and heavy-flavor $(Λ_{\rm c})$ baryon production is presented, together with a comparison to phenomenological models.
