Comparison of the hardest $k_{\mathrm{T,g}}$ jet splitting found using soft drop with z_cut = 0.2, beta = 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. The z_cut enables a larger kt range. Within uncertainties, the pp and semi-central PbPb are consistent with no modification at high kt, with a hint of modification at low kt.

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