Jet transport coefficients associated with fermionic two-point correlators in a weakly-coupled plasma

Abstract

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 $2\to 2$ 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.
