• jet-induced medium excitation
• baryon-to-meson ratio
• CoLBT-hydro model

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 Lambda/k(s)(0) in jet in Pb-Pb collisions at root s(NN) = 2.76 TeV. We qualitatively describe the enhancement of the Lambda/k(s)(0) ratio in jet in the intermediate pT region due to the contribution from jet-induced medium flow.
