Heavy-Quark Spectra at RHIC and Resonances in the QGP Original Research Article

Thermalization and collective flow of charm (c) and bottom (b) quarks are evaluated from elastic parton scattering via “D”- and “B”-meson resonances in an expanding, strongly interacting quark-gluon plasma at RHIC. Pertinent drag and diffusion coefficients are implemented into a relativistic Langevin simulation to compute transverse-momentum spectra and azimuthal flow asymmetries (v2) of c- and b-quarks. Upon hadronization (including coalescence and fragmentation) and semileptonic D- and B-decays, the resulting electron spectra (RAA and v2) are compared to recent RHIC data.
