We present the first inclusive measurements of the invariant and softdrop jet mass in proton-proton collisions at $\sqrt{s}=200\text{ }\text{ }\mathrm{GeV}$ at STAR. The measurements are fully corrected for detector effects, and reported differentially in both the jet transverse momentum and jet radius parameter. We compare the measurements to established leading-order …
