“…The comparison of our results with pQCD models [14] shows that the energy loss of a jet parton in the non-perturbative QCD medium (as characterized by the DQPM) occurs stronger [3] than by scattering with massless pQCD partons. Furthermore, at large 𝑇 our results for q are in qualitative agreement with pQCD results, with lattice results (pure SU(3) and (2+1)-flavor) as well as with phenomenological estimates by the JET and JETSCAPE collaborations and the Color String Percolation Model.…”

“…Recently in Ref. [3] we have evaluated the jet transport coefficients -the transverse momentum transfer squared per unit length q as well as the energy loss per unit length Δ𝐸 = 𝑑𝐸/𝑑𝑥, using an effective field-theoretical model -the dynamical quasiparticle model (DQPM) [4][5][6][7][8]. In this study we concentrate on the energy loss of jet partons due to elastic scattering, which is expected to be the dominant contribution at low and intermediate jet momenta.…”

We study the interaction of leading jet partons in a strongly interacting quark-gluon plasma (sQGP) medium based on the effective dynamical quasiparticle model (DQPM). The DQPM describes the non-perturbative nature of the sQGP at finite temperature 𝑇 and baryon chemical potential 𝜇 𝐵 based on a propagator representation of massive off-shell partons (quarks and gluons) whose properties (characterized by spectral functions with 𝑇, 𝜇 𝐵 dependent masses and widths) are adjusted to reproduce the lattice Quantum Chromodynamics (lQCD) EoS for the QGP in thermodynamic equilibrium. We present the results for the jet transport coefficients, i.e. the transverse momentum transfer squared per unit length q in the QGP and investigate their dependence on the medium temperature 𝑇 and jet parton energy.

“…Furthermore, we noticed that q exhibited a significant increase with the momentum of the jets, indicating a strong momentum dependence. In comparison to pQCD models [12], our results indicate that the energy loss experienced by a jet parton in the non-perturbative QCD medium (characterized by the DQPM) is stronger [3] when compared to scattering with massless pQCD partons. Additionally, for large temperatures, our q results demonstrate qualitative agreement with pQCD results, lattice results (both pure SU(3) and (2+1)-flavor), as well as with estimates from phenomenological studies by the JET and JETSCAPE collaborations and the Color String Percolation Model.…”

We investigate the interaction of leading jet partons within a strongly interacting quark-gluon plasma (sQGP) medium, using the effective dynamical quasiparticle model (DQPM). The DQPM offers a description of the sQGP's non-perturbative nature at finite temperature 𝑇 and baryon chemical potential 𝜇 𝐵 through a propagator representation of massive off-shell partons (quarks and gluons). These partons are characterized by spectral functions with 𝑇, 𝜇 𝐵 dependent masses and widths, adjusted to reproduce the lattice Quantum Chromodynamics (lQCD) equation-of-state (EoS) for the QGP in thermodynamic equilibrium. Our focus lies on examining the jet transport coefficients by elastic scattering in sQGP, specifically the transverse momentum transfer squared per unit length denoted as q, within the QGP. Furthermore, we investigate the dependence of these coefficients on both the medium temperature 𝑇 and the jet parton energy. By studying the jet transport coefficients and their relationship to temperature and parton energy, we aim to gain insights into the dynamics of jet propagation in the strongly interacting quark-gluon plasma medium.

I present an overview of recent developments in the microscopic description of the quark-gluon plasma. I will concentrate on medium-induced emission and transverse momentum broadening. These are two key ingredients of the theory of jet modifications in the QCD medium and of the kinetic theory used for transport and thermalisation. The main focus is on progress towards a better understanding of theory and of its uncertainties.
