论文摘要
报告了新的星形差异和整体v {2,3}测量值，这些测量值是针对P/D/3HE+AU明确解释非流量贡献的，Roots collisions = 200 GEV。该测量值在串联中利用P/D/D/3HE+AU的两粒子相关因子和最小偏置的P+P碰撞，并与三种良好的非流量减法方法相关。对于可比较的多样性，它们进一步指出了与系统无关的V2 {2}和V3 {2}值，这些值与大小（n {ch}）的关键作用以及亚核 - 核 - 触发驱动的偏心率E {2,3}相一致，但与p/d/d/d/d/3he collistion collistion collistion e {2,3}相关。从测量结果得出的缩放函数，确认最终状态效应在各种碰撞系统大小和能量中的重要作用，并建议对小型碰撞系统的ETA/S（T，MUB）增加。
New STAR differential and integral v{2,3} measurements that explicitly account for non-flow contributions are reported for p/d/3He+Au, collisions at Roots=200 GeV. The measurements, which leverage the two-particle correlators for p/d/3He+Au and minimum-bias p+p collisions in tandem with three well-established methods of non-flow subtraction, are observed to be method-independent. For comparable multiplicities, they further indicate system-independent v2{2} and v3{2} values that are consistent with the critical role of both size (N{ch}) and the subnucleonic-fluctuations-driven eccentricities e{2,3} but are inconsistent with the notion of shape engineering in p/d/3He+Au collisions. The scaling function derived from the measurements, confirm the important role of final-state effects across a broad spectrum of collision-system sizes and energies and suggests an increase in eta/s(T,muB) for small collision-systems.
