Jet shape and redistribution of the lost energy from jets in Pb+Pb collisions at the LHC in a multiphase transport model

Understand

Jet-medium interaction involves two important effects: jet energy loss and medium response.

• The search for jet-induced medium excitations is one of the hot topics in jet quenching study in relativistic nuclear collisions.
• In this work, we perform a systematic study on how the lost energy from hard jets evolves with the bulk medium and redistributes in the final state of heavy-ion collisions via a multi-phase transport model.
• In particular, the ($\Delta \eta, \Delta \phi$) distribution of charged particles with respect to the jet axis and jet shape function are studied for various Pb+Pb collision centralities and for different transverse momentum intervals of charged particles.
