Elliptic and triangular flow of heavy flavor in heavy-ion collisions

Understand

We investigate the elliptic and the triangular flow of heavy mesons in ultrarelativistic heavy-ion collisions at RHIC and the LHC.

• The dynamics of heavy quarks is coupled to the locally thermalized and fluid dynamically evolving quark-gluon plasma.
• The elliptic flow of $D$ mesons and the centrality dependence measured at the LHC is well reproduced for purely collisional and bremsstrahlung interactions.
• Due to the event-by-event fluctuating initial conditions from the EPOS2 model, the $D$ meson triangular flow is predicted to be nonzero at $\sqrt{s}=200$ GeV and $\sqrt{s}=2.76$ TeV.
