AI中文摘要:
我们利用两种互补方法研究质心系核子-核子能量$\sqrt{s_{NN}}=5.02$TeV的重离子碰撞中$\phi(1020)$和$\Omega(1672)$的产生。第一种方法采用并合模型讨论$\phi$和$\Omega$的产生;第二种方法开发了一种混合框架,将喷注部分子与热部分子的重组和剩余弦碎裂相结合。夸克胶子等离子体中的热部分子用 blast-wave 参数化建模,而介质修正喷注的相空间信息由 Q-PYTHIA 生成,使用从 HIJING 初始输入得到的未淬灭喷注部分子。我们表明两种方法均与实验测量结果吻合良好,且该混合框架能为相对论重离子碰撞中$\phi$和$\Omega$产生的潜在奇异成分提供更深入的见解。
英文摘要:
We study the production of the $ϕ(1020)$ and $Ω(1672)$ in heavy ion collisions at $\sqrt{s_{NN}} = 5.02$ TeV by employing two complementary approaches. In the first approach, the production of the $ϕ$ and $Ω$ is discussed in the coalescence model. In the second approach, we developed a hybrid framework that combines the recombination of shower and thermal partons with remnant string fragmentation. Thermal partons in the quark-gluon plasma are modeled using a blast-wave parameterization, while the phase space information of medium-modified parton showers is generated from Q-PYTHIA, using unquenched jet partons obtained from HIJING initial inputs. We show that both approaches agree well with the experimental measurements, and demonstrate that this hybrid framework provides deeper insight into the underlying strangeness components in the production of $ϕ$ and $Ω$ in relativistic heavy-ion collisions.
