英文摘要	Within a multiphase transport model with a string-melting scenario, the jet transport parameter q<^> is extracted in Au+Au collisions at sNN= 200 GeV and Pb+Pb collisions at sNN= 2.76 TeV. The jet transport parameter q<^> is a key parameter in jet-quenching phenomena, which depends not only on the temperature of the QCD medium but also on jet energy. We observe that q<^> increases with increasing of the jet energy for both the partonic phase and the hadronic phase. The energy and path length dependences of q<^> in full heavy-ion evolution are consistent with the expectations of jet quenching. The correlation between jet transport parameter q<^> and dijet transverse momentum asymmetry AJ is investigated. It is interesting to find that dijets with larger AJ have larger length-averaged q<^> values. Our study suggests that dijets with different AJ values can provide versatile tools for studying jet quenching and extracting jet transport parameters.
