Abstract (english)	: We report about the properties of the underlying event measured with ALICE at the LHC in pp and p–Pb collisions at √ sNN = 5.02 TeV. The event activity, quantified by charged-particle number and summed-pT densities, is measured as a function of the leadingparticle transverse momentum (p trig T ). These quantities are studied in three azimuthalangle regions relative to the leading particle in the event: toward, away, and transverse. Results are presented for three different pT thresholds (0.15, 0.5 and 1 GeV/c) at midpseudorapidity (\|η\| < 0.8). The event activity in the transverse region, which is the most sensitive to the underlying event, exhibits similar behaviour in both pp and p–Pb collisions, namely, a steep increase with p trig T for low p trig T , followed by a saturation at p trig T ≈ 5 GeV/c. The results from pp collisions are compared with existing measurements at other centre-ofmass energies. The quantities in the toward and away regions are also analyzed after the subtraction of the contribution measured in the transverse region. The remaining jet-like particle densities are consistent in pp and p–Pb collisions for p trig T > 10 GeV/c, whereas for lower p trig T values the event activity is slightly higher in p–Pb than in pp collisions. The measurements are compared with predictions from the PYTHIA 8 and EPOS LHC Monte Carlo event generators.
