We use CoLBT-hydro model for simultaneous event-by-event simulations of jet propagation and hydrodynamics evolution of the bulk medium including jet-induced medium excitation. The final reconstructed jet in heavy-ion collision include not only hadrons from medium response for the deposited energy and momentum of hard partons, but also hadrons from the fragmentation and recombination process of in-medium hard partons. We carry out the study with CoLBT-hydro of medium modification of the Λ/k0s in jet in Pb-Pb collisions at sNN=2.76TeV. We qualitatively describe the enhancement of the Λ/k0s ratio in jet in the intermediate pT region due to the contribution from jet-induced medium flow.
