  • 摘要: 应用多源热模型研究了相对论性重离子对撞机(RHIC)上PHENIX合作组测得的每核子对质心能量√sNN=200 GeV的氘-金(d+Au)碰撞中快度长程方位角关联,和大型强子对撞机(LHC)上CMS合作组测得的质心能量√s=0.9,2.36,7 TeV的质子质子(p+p)碰撞中高多重数短程赝快度关联,在误差范围内模型结果很好地重现了实验数据。用4个参数分析了长程方位角关联,结果表明,参数可以清楚地显示出脊结构的变化趋势,说明脊结构与集体效应、流体力学流效应、粒子对的横动量及信号等有关。用3个参数分析了小系统高多重数短程赝快度关联,结果表明,参数σc3与能量相关,能量越大,两粒子越靠近,关联越强。


    The multi-source thermal model is used in this paper to analyze the long-range azimuth correlation in deutron-gold (d+Au) collisions at center-of-mass energy per nucleon pair √sNN=200 GeV measured by the PHENIX Collaboration at the relativistic heavy ion collider (RHIC), and the short-range pseudorapidity correlation in high multiplicity event in proton-proton (p+p) collisions at center-of-mass energy √s=0.9, 2.36, 7 TeV measured by the CMS Collaboration at the large hadron collider (LHC). The modeling results are in approximately agreement with the experimental data in error ranges. Four parameters are used in the analysis of long-range azimuth correlation, which show that the parameters describe the change trend of ridge structure. The ridge structure is related to the collective effect, hydrodynamic flow effect, transverse momentum and signal of particle pair, and so forth. Three parameters are used in the analysis of the short-range pseudorapidity correlation in high multiplicity event in small system, which show that the parameters σ and c3 are related to collision energy. Large collision energy results in strong correlation due to close distance between particles.
