Figure Caption

Upper panel: the summed- $p_{\rm T}$ density as a function of $p_{\rm T}^{\rm trig}$ in pp and pPb collisions in jet-like signal, toward region with transverse momentum threshold $p_{\rm T} > 0.5 $ GeV/$c$. Results for data and comparison with models PYTHIA 8 (green) and EPOS LHC (red) predictions for the toward regions, after the subtraction of the charged-particle number density in the transverse region, are shown. Bottom panel: charged-particle number density measured in pp collisions divided by those in pPb collisions are displayed for both data and models.
