AI中文摘要:
通过使用参考文献[arxiv 2608.17160, arxiv 2608.17161]中发展的方法计算树级领头阶$2\to2$散射率及其矩,我们获得了一组新的喷注-介质输运系数,这些系数源于涉及Glauber夸克的喷注-介质交换,并编码在$\hat{\mathcal{F}}_i$中[Phys. Rev. C 111, 054913 (2025), Phys. Rev. C 113, 055207]。在此观察到喷注-介质输运系数和散射率对领头对数依赖的显著偏离,正如参考文献[arxiv 2608.17160, arxiv 2608.17161]先前所述。我们获得了$\hat{\mathcal{F}}_i$的闭式表达式,其精度优于$\lesssim 10\\%$,从而使我们的方法可用于喷注-介质相互作用的蒙特卡罗模拟。包含$\hat{\mathcal{F}}_i$的蒙特卡罗模拟对风味流体动力学化动力学敏感,因为核-核碰撞中产生的介质从早期Glasma动力学过渡到夸克-胶子等离子体流体。
英文摘要:
A new set of jet-medium transport coefficients stemming from jet-medium exchanges involving Glauber quarks encoded in $\hat{\mathcal{F}}_i$ [Phys. Rev. C 111, 054913 (2025), Phys. Rev. C 113, 055207] are obtained by computing the tree-level leading-order $2\to2$ scattering rates and their moments using the approach developed in Refs. [arxiv 2608.17160, arxiv 2608.17161]. Sizeable deviations away from the leading logarithmic dependence of jet-medium transport coefficients and scattering rate are observed here, as previously mentioned in Refs.[arxiv 2608.17160, arxiv 2608.17161]. A closed-form expression for $\hat{\mathcal{F}}_i$ accurate to $\lesssim 10$\% or better is obtained, enabling our approach to be used within Monte Carlo simulations of jet-medium interactions. Monte Carlo simulations incorporating $\hat{\mathcal{F}}_i$ are sensitive to flavor hydrodynamization dynamics as the medium created in nucleus-nucleus collisions transitions from the early-time Glasma dynamics to the quark-gluon plasma fluid.
