质心系能量200 GeV下Au-Au碰撞中的轻核产生
Productions of light nuclei in Au-Au collisions at √sNN=200 GeV
摘要
Abstract
Recently,Collaboration S published a few data of light nuclei such as deuterons and tritons in Au-Au collisions at RHIC.This provides a new opportunity for further exploring the production mecha-nism of light nuclei.Here,the nucleon coalescence model is employed to systematically study the trans-verse momentum spectra,yield rapidity densities and the averaged transverse momenta of d,t and 3He in Au-Au collisions at √sNN=200 GeV.The theoretical results can naturally explain the experimental data of d and t and provide reference for further measurement of 3 He.All the results show that the nucleon coales-cence is the dominant production source for light nuclei production at RHIC.关键词
