Linearized Boltzmann transport model for jet propagation in the quark-gluon plasma: Heavy quark evolution

Understand

A Linearized Boltzmann Transport (LBT) model coupled with hydrodynamical background is established to describe the evolution of jet shower partons and medium excitations in high energy heavy-ion collisions.

• We extend the LBT model to include both elastic and inelastic processes for light and heavy partons in the quark-gluon plasma.
• A hybrid model of fragmentation and coalescence is developed for the hadronization of heavy quarks.
• Within this framework, we investigate how heavy flavor observables depend on various ingredients, such as different energy loss and hadronization mechanisms, the momentum and temperature dependences of the transport coefficients, and the radial flow of the expanding fireball.
