Abstract
Within a multi-phase transport model with string melting scenario, jet transport parameter is calculated in Au+Au collisions at = 200 GeV and Pb+Pb collisions at = 2.76 TeV. The increases with the increasing of jet energy for both partonic phase and hadronic phase. The energy and path length dependences of in full heavy-ion evolution are consistent with the expectations of jet quenching. The correlation between jet transport parameter and dijet transverse momentum asymmetry is mainly investigated, which discloses that a larger corresponds to a larger . It supports a consistent jet energy loss picture from the two viewpoints of single jet and dijet. It is proposed to measure dijet asymmetry distributions with different jet transport parameter ranges as a new potential method to study jet quenching physics in high energy heavy-ion collisions.
