Comparison of the hardest $k_{\mathrm{T,g}}$ jet splitting found using dynamical grooming a = 1.0 for R = 0.2 jets in pp and 30-50% PbPb collisions at 5 TeV. The range of the semi-central PbPb is determined by requiring sufficient subjet purity and kinematic efficiency. Within uncertainties, the pp and semi-central PbPb are consistent with no modification.

The ratio is compared with hybrid model predictions with and without Moliere scattering. The data are consistent with both predictions.
