Comparison of the hardest $k_{\mathrm{T,g}}$ jet splitting found using dynamical grooming a = 1.0 z > 0.2 for R = 0.2 jets in pp and 0-10% PbPb collisions at 5 TeV. The range of the central PbPb is determined by requiring sufficient subjet purity and kinematic efficiency. The central PbPb is modified compared to the pp

The ratio is compared with hybrid model predictions with and without Moliere scattering, as well as JETSCAPE v3.5 AA22. The data are appear to prefer without Moliere, and are consistent with the JETSCAPE predictions
