Jets from early stages of heavy-ion collisions undergo modified showering in quark-gluon plasma (QGP) relative to vacuum due to jet-medium interactions, which can be measured using observables like differential jet shape and generalized angularities. Differential jet shape (\(\rho(\mathbf{r})\) ) encodes radially differential information about jet broadening and has shown an average migration of charged energy away from the axes of quenched jets from Pb+Pb collisions at the LHC. Measurements of generalized angularities in presence of the medium from Pb+Pb collisions at the LHC show harder, or more quark-like jet fragmentation relative to vacuum. Measuring these distributions in heavy-ion collisions at RHIC will help us further characterize jet-medium interactions in a phase-space region complementary to that of the LHC.

In these proceedings, we present the first fully corrected measurements of (\(\rho(\mathbf{r})\)) , jet girth (g), momentum dispersion (\(\rm p_T^D\)) and momentum difference of leading and subleading constituent particles (LeSub) observables, using hard-core jets in p + p collisions at \(\sqrt{s} = 200\ \mathrm{GeV}\), collected by the STAR experiment. Finally, the data are compared with model calculations and the physics implications are discussed.
