The Signal (TT{20}{30}) and Reference (TT{6}{7}) trigger-normalized recoil jet distributions and the corresponding $\Delta_{\rm recoil}$ distribution for MB and HM pp collisions at $\sqrts = 13$ TeV. Left panels: projection onto $p_{\rm T,jet}^{\rm reco, ch}$ for $|\Delta\varphi-\pi|<0.6$. Middle and right panels: projection onto $\Delta\varphi$ in two $p_{\rm T,jet}^{\rm reco, ch}$ intervals.
