abstract

We supply recently obtained results from lattice EQCD with the correct UV limit to construct the collisional broadening kernel $C(b_\perp)$ in a QCD plasma. We discuss the limiting behavior of $C(b_\perp)$ at small and large impact parameters $b_\perp$, and illustrate how the results can be used to compute medium-induced radiation rates.

  1. Jet broadening and radiation in the early anisotropic plasma in heavy-ion collisions

    hep-ph 2025-09 conditional novelty 7.0 of 10

    The full angle-dependent jet-medium collision kernel is extracted from QCD kinetic theory for the pre-equilibrium plasma, revealing strong early-time anisotropy and up to 300% error in the isotropic splitting rates us...

  2. Gluon radiation from a QCD antenna with realistic parton-medium interactions

    hep-ph 2026-07 unverdicted novelty 6.0 of 10

    The in-medium antenna gluon spectrum is obtained by numerical solution of Dyson-type equations that fully resum multiple scatterings for Yukawa and HTL rates, without harmonic-oscillator or opacity truncations.

  3. Jet momentum broadening beyond the jet quenching parameter from QCD kinetic theory

    hep-ph 2025-09 conditional novelty 5.0 of 10

    The full elastic collision kernel for jet broadening in the pre-equilibrium gluon plasma is enhanced at small momentum transfer compared to thermal equilibrium, particularly along the beam axis.

  5. What is the Quark-Gluon Plasma made of?

    nucl-th 2025-06 accept novelty 2.0 of 10

    The quark-gluon plasma is best described as a strongly coupled liquid of massive, very short-lived quark and gluon quasiparticles, with sound (phonon) modes becoming the most well-defined collective excitation at low momenta.
