Fully-corrected $\Delta_{\rm recoil}$ distributions measured in MB and HM-selected events in pp collisions at $\sqrts=13$ TeV. Left panel: $\Delta_{\rm recoil}(p_{\rm T,jet}^{\rm ch})$ in $|\Delta\varphi-\pi|<0.6$; middle and right panels: $\Delta_{\rm recoil}(\Delta\varphi)$ for $20<p_{\rm T,jet}^{\rm ch}<40$ GeV/$c$ and $40<p_{\rm T,jet}^{\rm ch}<60$ GeV/$c$. Also shown are particle-level simulated distributions calculated with PYTHIA 8 Monash tune, and a pQCD calculation at LO with Sudakov broadening (MB $\Delta_{\rm recoil}(\Delta\varphi)$ only). The width of the PYTHIA 8 HM band represents the statistical uncertainty. Top row: $\Delta_{\rm recoil}$ distributions; middle row: ratio of $\Delta_{\rm recoil}$ distributions for HM/MB from data; bottom row: Data/PYTHIA 8 separately for MB and HM event selections.
