Heavy-quark suppression and anisotropic flow at intermediate momentum

Year: 2025

Type: article

Abstract: In an intermediate-momentum regime where mass effects are significant, heavy-quark suppression and anisotropic flow are computed to investigate the transition between the collisional and radiative energy losses. Based on the collision kernel for diffusion, elastic scattering and semicollinear gluon bremsstrahlung can be consistently incorporated into a Boltzmann equation that involves the heavy-quark diffusion coefficient. Using the running coupling constant and the diffusion coefficient constrained by lattice QCD data, the collisional and radiative energy-loss contributions to the R A A and v 2 are studied in hydrodynamically expanding thermal media. The evolution of the observables, the bulk flow effect, and the dependence on mass and centrality are discussed in noncentral heavy-ion collisions.
