| dc.description | We revisit the question of the measured, unexpectedly large, heavy flavor suppression, $R_{AA}(p_T) \ll 1$, in nucleus-nucleus collisions at RHIC and compare two new theoretical approaches to the $D$- and $B$-meson quenching. In the first model, radiative energy loss, collisional energy loss and heavy quark-resonance interactions are combined to evaluate the drag and diffusion coefficients in the quark-gluon plasma and the mixed phase. These are applied in a relativistic Fokker-Planck equation to simulate the heavy $c$- and $b$-quark suppression rate and elliptic flow $v_2(p_T)$. In the second model, the fragmentation probability for heavy quarks and the medium-induced decay probability for heavy hadrons are derived. These are implemented in a set of coupled rate equations that describe the attenuation of the observable spectra from the collisional dissociation of heavy mesons in the QGP. An improved description of the non-photonic electron $R_{AA}(p_T)$ at RHIC can be obtained. In contrast to previous results, the latter approach predicts suppression of $B$-mesons comparable to that of $D$-mesons at transverse momenta as low as $p_T \sim 10$ GeV. | |
