Charged-particle number density as a function of $p_{\rm T}^{\rm trig}$ measured in pp (left) and p-Pb collisions (right) at $\sqrt{s_{\rm NN}}=5.02$ TeV. Measurements were performed considering associated charged particles with $\pt>0.5$ GeV/$c$. Results for the toward, transverse, and away regions are displayed. The coloured boxes and the error bars represent the systematic and statistical uncertainties, respectively.
