Heavy-quark suppression and anisotropic flow at intermediate momentum
Abstract
We discuss heavy quark diffusion and radiation in an intermediate-momentum regime where the heavy-quark mass is non-negligible. Based on the collision kernel for diffusion, elastic scattering and semicollinear gluon-bremsstrahlung can be consistently incorporated into a Boltzmann equation that employs the heavy quark diffusion coefficient as its single transport parameter. Using the diffusion coefficient constrained by lattice QCD data, we estimate the nuclear modification factor and the elliptic flow induced by the collisional and radiative energy loss of heavy quarks, and analyze their dependence on momentum and impact parameter.
