（武汉）高能核-核碰撞中轻反核物质和奇特物质的产生.ppt

Summary 中国物理学会高能物理分会第九届全国会员代表大会暨学术年会 We proposed a dynamically constrained phase space coalescence model to calculate the light (anti)nuclei in high enerngy collisions, The results turned out that it would be an effective method investigating the production of light (anti)nuclei in high energy collisions. Predict the light (anti)nuclei yield, transverse momentum and the rapidity distribution in pp collisions at √s = 7 and 14 TeV . Study centrality dependence of light anti-nuclear produced in Au+Au collisions. Discussed the scaling properties of light antinuclei production in Au+Au collisions. * Thanks for yourattention! * * Larry,Robert. Pisarski,NPA 796, 83, 2007.
