Anisotropy flows in Pb-Pb collisions at LHC energies from parton scatterings with heavy quark trigger

By implementing an additional heavy quark-antiquark pair production trigger in a multiphase transport (AMPT) model, we study the effect on anisotropy flows of identified particles with a focus on charged particles and quarkonium (J/psi and (sic)). A systematic increase in the collision rate for active partons in the AMPT model with such an implementation has been observed. It leads to a slight increase of identified particles anisotropy flows as a function of transverse momentum (p(T)) and rapidity, and gives a better description of the experimental data of elliptic flow toward larger p(T). Our approach provides an efficient way to study the heavy quark dynamics in the AMPT model at LHC energies.
