在RHIC从STAR产生奇异强子的束流能量依赖性

Beam energy dependence of strange hadron production from STAR at RHIC

Xiaoping Zhang

摘要:

利用BNL相对论重离子对撞机(RHIC)的束流能量扫描(BES)计划,对\sqrt{s_{NN}} = 7.7,11.5,19.6,27和39 GeV的Au+Au碰撞中快度K^{0}_{S},ε,Λ,ε和Ω进行了STAR测量.核修正因子和重子介子比的测量,以了解重组和部分子能量损失机制。部分子与强子动力学在低束能量的影响进行了讨论。

英文摘要:

We present STAR measurements of K^{0}_{S}, ϕ, Λ, Ξ, and Ωat mid-rapidity from Au+Au collisions at \sqrt{s_{NN}} = 7.7, 11.5, 19.6, 27, and 39 GeV from the Beam Energy Scan (BES) program at the BNL Relativistic Heavy Ion Collider (RHIC). Nuclear modification factors and baryon-to-meson ratios are measured to understand recombination and parton energy loss mechanisms. Implications on partonic versus hadronic dynamics at low beam energies are discussed.
