Systematic Studies of Jet-medium Interactions in STAR

In these proceedings, we report recent jet results from STAR in heavy-ion collisions. The first measurement of centrality dependence of di-jet momentum imbalance AJ at RHIC is presented. An apparent evolution of the AJ distributions from central to peripheral collisions is observed. A new di-hadron...

Summary:In these proceedings, we report recent jet results from STAR in heavy-ion collisions. The first measurement of centrality dependence of di-jet momentum imbalance AJ at RHIC is presented. An apparent evolution of the AJ distributions from central to peripheral collisions is observed. A new di-hadron correlation measurement with a method to subtract all orders of flow background using data themselves is also presented to study how the lost energy of jets is redistributed to particles with low-to-modest transverse momentum.
