论文摘要
我们解决收益率$ \ rm s_3 $ = $ \ rm \ frac {n _ {^3_λH}/n_λ} { $ \ rm \ sqrt {s_ {nn}} $ = 2.76 TEV,通过对au+au碰撞中的弱衰减贡献的不同处理,以$ \ rm \ rm \ sqrt {s_ {s_ {nn}}} $ = 200 gev。然后,我们使用合并模型来提取有关重离子碰撞动力学冻结时$λ$和核子密度波动的信息。我们还从可用的实验数据中显示,产量比$ \ rm S_2 $ = $ \ rm \ rm \ frac {n _ {^^3_λH}} {n_λn_d} $比$ \ rm S_3 $更有前途的可观察到,用于探测本地Baryon-trangens trangeness Inter of in Procatency Med Med中。
We resolve the difference in the yield ratio $\rm S_3$ = $\rm \frac{N_{^3_ΛH}/N_Λ}{N_{^3He}/N_p}$ measured in Au+Au collisions at $\rm \sqrt{s_{NN}}$ = 200 GeV and in Pb-Pb collisions at $\rm \sqrt{s_{NN}}$ = 2.76 TeV by adopting a different treatment of the weak decay contribution to the proton yield in Au+Au collisions at $\rm \sqrt{s_{NN}}$ = 200 GeV. We then use the coalescence model to extract information on the $Λ$ and nucleon density fluctuations at the kinetic freeze-out of heavy ion collisions. We also show from available experimental data that the yield ratio $\rm S_2$ = $\rm \frac{N_{^3_ΛH}}{N_ΛN_ d}$ is a more promising observable than $\rm S_3$ for probing the local baryon-strangeness correlation in the produced medium.
