Event-by-event fluctuations of the mean transverse momentum (mean-pT) provide a sensitive probe of collective dynamics beyond single-particle spectra and anisotropic flow. We present a systematic study of mean-pT fluctuation observables using a Bayesian-calibrated multistage hydrodynamic framework, including quantitative comparisons to RHIC measurements and model-based investigations of beam-energy and kinematic-acceptance effects. The experimental definitions employed by the STAR and ALICE Collaborations are implemented explicitly and found to yield consistent results within controlled limits. We study the centrality and beam-energy dependence of the observable, its sensitivity to key soft-sector ingredients, and the impact of the kinematic pT acceptance. By introducing scaled-pT cuts, we demonstrate that a part of the apparent energy dependence arises from kinematic projection effects, while the remaining trends reflect genuine collective dynamics. Our results establish mean-pT fluctuations as a nontrivial and independent validation of calibrated hydrodynamic descriptions of the quark–gluon plasma.
平均横向动量（mean- pt）的事件-事件波动提供了超越单粒子光谱和各向异性流的集体动力学的敏感探针。我们使用贝叶斯校准的多级水动力框架对平均pt波动观测值进行了系统研究，包括与RHIC测量值的定量比较以及基于模型的光束能量和运动学接受效应的研究。STAR和ALICE合作采用的实验定义是明确实施的，并发现在控制范围内产生一致的结果。我们研究了可观测的中心性和光束能量依赖性，其对关键软成分的敏感性，以及运动学pT接受度的影响。通过引入比例pt切割，我们证明了部分明显的能量依赖来自运动学投影效应，而其余的趋势反映了真正的集体动态。我们的结果建立了平均pt波动作为校准夸克-胶子等离子体的流体动力学描述的非平凡和独立验证。
