论文摘要
短寿命的耐药共振的测量用于研究PP,P-A和相对论重离子碰撞中粒子产生和碰撞动力学的不同方面。共振的产率对强子撤离和再生的竞争过程敏感,从而使这些颗粒对晚期辐射阶段的性质的独特探针具有独特的探针。具有不同质量和量子数的共振的测量还提供了对陌生产生和过程的洞察力,这些过程确定了中间横向动量上粒子动量光谱的形状,以及在高动量下强子抑制的物种依赖性。我们在爱丽丝实验中介绍了全面的结果,并以$ρ(770)^{0} $,k $^{*}(892)$,$ ϕ(1020)$,$σ(1385)^{\ pm} $,$λ(\ pm} $,$λ(1520)$,$λ(1520)$,$λ(1520)$ pp pp pp,能量范围内的XE-XE和PB-PB碰撞$ \ sqrt {s _ {\ rm nn}} $ = 2.76-13 TEV,包括LHC运行2的最新测量结果。所获得的结果用于研究系统尺寸和碰撞的次数进化率和核模型和核模型的核对率和核心比例的碰撞进化和核心比例和核心比例的进度和核心比例的进度和核心比例的进度。我们将这些结果与降低能量测量结果进行比较,并在可用的情况下进行模型计算。
Measurement of short-lived hadronic resonances are used to study different aspects of particle production and collision dynamics in pp, p-A and relativistic heavy-ion collisions. The yields of resonances are sensitive to the competing processes of hadron rescattering and regeneration, thus making these particles unique probes of the properties of the late hadronic phase. Measurements of resonances with different masses and quantum numbers also provide insight into strangeness production and processes that determine the shapes of particle momentum spectra at intermediate transverse momenta, as well as the species dependence of hadron suppression at high momentum. We present the comprehensive set of results in the ALICE experiment with unprecedented precision for $ρ(770)^{0}$, K$^{*}(892)$, $ϕ(1020)$, $Σ(1385)^{\pm}$, $Λ(1520)$, and $Ξ(1530)^{0}$ production in pp, p-Pb, Xe-Xe and Pb-Pb collisions in the energy range $\sqrt{s_{\rm NN}}$ = 2.76-13 TeV, including the latest measurements from LHC Run 2. The obtained results are used to study the system-size and collision-energy evolution of transverse momentum spectra, particle ratios and nuclear modification factors and to search for the onset of collectivity in small collision systems. We compare these results to lower energy measurements and model calculations where available.
