Figure Caption

Comparison of the hardest $k_{\mathrm{T,g}}$ jet splitting found using dynamical grooming a = 2.0 with z > 0.2 for R = 0.2 jets in pp, 0-10% PbPb and 30-50% PbPb collisions at 5 TeV. The range of th PbPb is determined by requiring sufficient subjet purity and kinematic efficiency. The z_cut enables a larger kt range. Within uncertainties, we see an overall modification of the measured $k_{\mathrm{T,g}}$ relative to pp in both semi-central and central PbPb
