Comparison of near- and away-side per-trigger yields (first row) and widths (third row) as a function of $\pt^{\rm{assoc}}$ for $4 < \pt^{\rm e} < 12$ \GeVc  in pp collisions at $\sqrt{s} = 5.02$ TeV and p--Pb collisions at $\sqrt{s_{\rm{NN}}} = 5.02$ TeV. The ratios between pp and p--Pb yields and widths are shown in the second and fourth row, respectively. The statistical (systematic) uncertainties are shown as vertical lines (empty boxes).
