Description
Recent STAR's jet physics results in heavy-ion collisions will be reported in this talk. Coincidence measurements of semi-inclusive jets recoiling from high-$p_T$ hadrons or direct photons will be presented to offer constraints on path length and flavor dependence of energy loss. Di-jets selected with a constituent cut of 2 GeV/$c$ showed significant transverse momentum imbalance which could be recovered from soft constituents to the level of p+p collisions within the original $R=0.4$ cone. Di-hadron correlation measurements with a method to subtract all orders of flow background using data themselves will also be presented to study how the lost energy is redistributed at low to modest $p_T$. We will contextualize and discuss recent and new systematic studies of jet coincidence and correlation measurements at STAR, taking advantage of the tenfold increase in statistics from recent data taking runs.
