论文摘要
重夸克是对热和密集的核物质的有效探针，即在超相关的重型离子碰撞中产生的夸克 - 糖浆等离子体。由于其生产的时间尺度很短，因此重型夸克体验了系统的整个演变。特别是，在LHC能量的PB-PB碰撞中，重型流动性强子产生的测量可以洞悉脱合物中重夸克运输的机制。在小型耐药系统（PP和P-PB碰撞）中，重型流动测量值为观察重装碰撞中热中等效应的基线提供了基准，以及测试扰动量子质量染色体动力学计算和冷 - 核对象效应的测量。在这一贡献中，讨论了各种能量的PP，P-PB和PB-PB碰撞中的开放重型流动强生产的最新结果。提出了针对完全重建的魅力哈登族的新测量结果，也针对重型富集体生衰变的单个电子，还通过测量D Meson和Elector trom Beauty-Hadron腐烂的测量来调查美容夸克的产生。
Heavy quarks are effective probes of the hot and dense nuclear matter, the quark-gluon plasma, produced in ultra-relativistic heavy-ion collisions. Due to the short time scale characterising their production, heavy quarks experience the whole evolution of the system. In particular, measurements of heavy-flavour hadron production in Pb-Pb collisions at LHC energies give insight into the mechanisms of heavy-quark transport in the deconfined matter. In small hadronic systems, pp and p-Pb collisions, heavy-flavour measurements provide the baseline for observations of hot-medium effects in heavy-ion collisions, as well as tests of perturbative quantum chromodynamic calculations and measurements of cold-nuclear-matter effects. In this contribution, recent ALICE results on open heavy-flavour hadron production in pp, p-Pb and Pb-Pb collisions at various energies are discussed. New measurements are presented both for fully-reconstructed charmed hadrons and for single electrons from heavy-flavour hadron decays, also investigating the beauty-quark production via the measurement of D mesons and electrons from beauty-hadron decays.
