摘      要：Jet quenching has successfully served as a hard probe to study the properties of Quark-Gluon Plasma(QGP).As a multi-particle system,jets require time to develop from a highly virtual parton to a group of partons close to mass *** this study,we present a systematical analysis on the effects of this formation time on jet quenching in relativistic nuclear *** from initial hard scatterings were simulated with Pythia,and their interactions with QGP were described using a Linear Boltzmann Transport(LBT) model that incorporates both elastic and inelastic scatterings between jet partons and the thermal *** different estimations of the jet formation time were implemented and compared,including instantaneous formation,formation from single splitting,and formation from sequential splittings,before which no jet-medium interaction was *** found that deferring the jet-medium interaction with a longer formation time not only affects the overall magnitude of the nuclear modification factor of jets but also its dependence on the jet transverse momentum.
