Following the nonperturbative light-front Hamiltonian formalism developed in our preceding work [Li. et al. Phys. Rev. D 104, 056014 (2021)], we investigate the momentum broadening of a quark jet inside a SU(3) colored medium. We perform the numerical simulation of the real-time jet evolution in Fock spaces of a single quark, a quark-gluon state, and coupled quark- and quark-gluon states at various jet momenta p+ and medium densities. With the obtained jet light-front wave function, we extract the jet transverse momentum distribution, the quenching parameter, and the gluon emission rate. We analyze the dependence of momentum broadening on p+, medium density, color configuration, spatial correlation, and medium-induced gluon emission. For comparison, we also derive analytically the expectation value of the transverse momentum of a quark-gluon state in any color configuration and in an arbitrary spatial distribution in the eikonal limit. This work can help understand jet momentum broadening in the noneikonal regime.

Rapidity dependence of initial state geometry and momentum correlations in p+Pb collisions
Schenke, B.; Schlichting, S.; Singh, P. (American Physical Society (APS), 2022)Event geometry and initial state correlations have been invoked as possible explanations of long-range azimuthal correlations observed in high-multiplicity p+p and p+Pb collisions. We study the rapidity dependence of initial ... -
