Rapidity dependence of heavy-flavour production in heavy-ion collisions within a full 3+1 transport approach: quenching, elliptic and directed flow

We extend our POWLANG transport setup for the modelling of heavy-flavour production in heavy-ion collisions to the case of full 3+1 simulations, dropping the approximation of longitudinal boost-invariance of the background medium. This enables us to provide predictions for observables for which the rapidity dependence is essential in order to obtain a non-vanishing signal, like the directed flow v(1), and to get reliable results also for kinematic distributions of heavy-flavour particles at forward rapidity. We compare our predictions with experimental data obtained in Au-Au and Pb-Pb collisions at RHIC and at the LHC.

Automated summary

Researchers extended their POWLANG transport setup to model heavy-flavour production in heavy-ion collisions, allowing predictions for observables that require rapidity dependence and reliable study of kinematic distributions of heavy-flavour particles at forward rapidity. Comparisons were made with experimental data from Au-Au and Pb-Pb collisions at RHIC and the LHC.
