We study the polarization of produced Λ in s=200GeV polarized proton-proton collision at RHIC/PHENIX, and also the polarization as a function of its rapidity which may be sensitivity to the quark heli...
We present the preliminary results on the spin alignment matrix
element ρ00 for vector mesons K*0(892) and
φ(1020) in mid-central (20%—60%) Au+Au and p+p collisions at sNN=200GeV. The values of ρ00 ...
√S=200GeV质子对撞中横质量谱劈裂效应的PYTHIA模拟研究
横质量谱 弦碎裂 独立碎裂 多重部分子交叉反应

Abstract在质心系能量为200GeV的质子－质子对撞中, 高横质量区域产生的强子横质量谱分裂成两类——重子和介子. 应用PYTHIA产生器进行Monte Carlo分析其内在的物理机制. 模拟结果表明, 这种劈裂效应不仅在弦碎裂模型中出现, 而且独立碎裂模型中也有, 并且在RHIC能区(200GeV)下主要来源于胶子的贡献. 在PYTHIA6.3版本中引入的新的物理机制表明复杂的弦纠缠(st...
