Recent measurements of jet substructure provide insights
into how the hard and soft parts of the jets are modified
by jet-medium interaction. One can also learn the flavor
dependence of jet quenching via comparisons between boson
tagged jet and inclusive jet. In this study, with the
Linear Boltzmann Transport (LBT) model, we investigate
the jet shape, jet splitting function and groomed jet
mass in single jet, photon-jet and heavy flavor jet
events. Our study on jet shape function shows that the
medium modifications for the core of quark jets and gluon
jets are quite different and the broadening of jet
profile at the edge of the jet cone is mainly carried by
soft particles from medium recoil. The groomed jet study
shows that jet induced medium response is responsible for
the enhancement of large groomed mass tail.We further
implement different scenarios of coherent and incoherent
energy losses in LBT simulation and find that they have a
significant impact on the pT dependence of the nuclear
modification of jet splitting function.
