摘要
采用新颖的横动量技术，分析 Ar+KCl 反应在 1.8 GeV/nucl 下带电粒子排他数据中的集体运动。此前采用标准球度张量的该反应分析未揭示显著效应。在本分析中观测到集体效应，其远强于 Cugnon 级联模型但弱于流体力学模型。

Preprint version, serving as a reference for another work (14 pages, 3 figures). This version contains, in particular, calculation of second-order azimuthal moments of particle distributions, in the elements of the sphericity tensor, not in the journal. The editor insisted on shortening of the paper, while the referee insisted on additional explanations, so something had to go
